I reckon this is relevant and rather concise.....
"He that BELIEVETH on the Son hath everlasting life:. . ." John 3:36
"For God so loved the world, that he gave his only begotten Son, that whosoever BELIEVETH in him should not perish, but have everlasting life." John 3:16
We are NOT saved by WORKS
The Bible makes it clear that OUR WORKS has nothing whatsoever to do with our salvation.
We don't receive it by our works — and we don't keep it by our works!
" NOT BY WORKS of righteousness which we have done, but according to his mercy he saved us,. . ." Titus 3:5
"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: NOT OF WORKS, lest any man should boast." Ephesians 2:8,9
Salvation is a FREE GIFT
Salvation is the free gift of God. If we had to work to keep it — it would not be a free gift — and God would be a liar!
". . . the GIFT of God is eternal life through Jesus Christ our Lord." Romans 6:23
". . .by the righteousness of one THE FREE GIFT came upon all men unto justification of life." Romans 5:18
Salvation is a NEW BIRTH.
Salvation is not enduring or a process, but an event in time. Salvation is a NEW BIRTH. Just as your first birth happened on a certain time and day, so does the second birth.
"(For he saith, I have heard thee in a TIME accepted, and in THE DAY OF SALVATION have I succoured thee: behold, now is the accepted TIME; behold, now is THE DAY OF SALVATION.)" 2 Corinthians 6:2
"Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be BORN AGAIN, he cannot see the kingdom of God." John 3:3
"Being BORN AGAIN, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever." 1 Peter 1:23
You become a CHILD OF GOD
Once you are born again SPIRITUALLY — you become a child of God.
"Beloved, NOW are we the SONS OF GOD, . . ." 1 John 3:2
"For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of ADOPTION, whereby we cry, Abba, FATHER." Romans 8:15
Nothing can SEPARATE us from our Father
Just as nothing can "negate" your physical birth, nothing can "negate" your spiritual birth.
My children will always be my children. We may have troubled times. Our fellowship may be broken, but our relationship can never be broken. They will always be my children. Nothing or nobody can change that! And once you are born again spiritually — God becomes your Father — nothing or nobody can change that! Your fellowship may be broken, but your relationship can never be broken!
"For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, SHALL BE ABLE TO SEPARATE US from the love of God, which is in Christ Jesus our Lord." Romans 8:38
"My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand." John 10:29
Jesus will NEVER leave us
Jesus promised He will never leave us. Jesus could not say this if there was even a chance of losing our salvation.
". . .for he hath said, I WILL NEVER LEAVE THEE, nor forsake thee." Hebrews 13:5
". . . and, lo, I am with you ALWAY, even unto the end of the world. Amen." Matthew 28:20
We already HAVE eternal life
When the Bible speaks of possessing eternal life, it speaks in the present tense (hath, have, etc.) — SOMETHING WE ALREADY HAVE! If we had to work or endure to keep our salvation, this could not be true.
"He that believeth on the Son HATH EVERLASTING LIFE:.. ." John 3:36
"These things have I written unto you that believe on the name of the Son of God; that ye may know that YE HAVE ETERNAL LIFE,. . ." 1 John 5:13
"Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, HATH EVERLASTING LIFE,. . ." John 5:24
Jesus will NOT cast you out
". . . him that cometh to me I WILL IN NO WISE CAST OUT." John 6:37
We are COMPLETE in Jesus Christ
"And ye are COMPLETE IN HIM, which is the head of all principality and power:" Colossians 2:10
We are PERFECTED FOR EVER
We are "perfected for ever" by Jesus Christ. How could the Lord say such a bold statement if we had to earn or keep our salvation?
"By the which will we are sanctified through the offering of the body of Jesus Christ ONCE FOR ALL. . . For by one offering he hath PERFECTED FOR EVER them that are sanctified." Hebrews 10:10,14
We are PRESERVED in Christ Jesus
"Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and PRESERVED IN JESUS CHRIST, and called:" Jude 1
"And THE LORD. . . WILL PRESERVE ME unto his heavenly kingdom:. . ." 2 Timothy 4:18
We are KEPT by the POWER of God
"Who are KEPT BY THE POWER OF GOD through faith unto salvation ready to be revealed in the last time." 1 Peter 1:5
"Now unto him that is able TO KEEP YOU from falling, and to present you faultless before the presence of his glory with exceeding joy," Jude 24
We are saved to the UTTERMOST
"Wherefore he is able also to save them to the UTTERMOST that come unto God by him,. . ." Hebrews 7:25
We are SEALED until the day of redemption
"And grieve not the holy Spirit of God, whereby YE ARE SEALED unto the day of redemption." Ephesians 4:30
". . .after that ye believed, YE WERE SEALED with that holy Spirit of promise," Ephesians 1:13
What about the BACKSLIDER?
What about the "backslider" or somebody that forsakes the Lord? The Bible says he will suffer loss (rewards, etc.) — but he himself shall be saved!
"For other foundation can no man lay than that is laid, which is Jesus Christ. Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble; Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is. If any man's work abide which he hath built thereupon, he shall receive a reward. If any man's work shall be burned, he shall suffer loss: BUT HE HIMSELF SHALL BE SAVED; yet so as by fire." 1 Corinthians 3:11-15
We become the BODY OF CHRIST
"For we are MEMBERS OF HIS BODY, of his flesh, and of his bones." Ephesians 5:30
"Now ye are the BODY OF CHRIST, and members in particular." 1 Corinthians 12:18
What if we later — BELIEVE NOT?
Our salvation is so secure — even if we BELIEVE NOT after we're saved, because we become part of Him (the body of Christ), ". . .yet he abideth faithful: HE CANNOT DENY HIMSELF."
"If we believe not, yet he abideth faithful: HE CANNOT DENY HIMSELF." 2 Timothy 2:13
But what if I sin an awful sin?
1 Corinthians 5 reports of an awful sin in the church. And even though Paul commands ". . . To deliver such an one unto Satan for the destruction of the flesh" — Paul still speaks of that person being saved — ". . .that the spirit MAY BE SAVED. . ."
"It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife. . .To deliver such an one unto Satan for the destruction of the flesh, that the spirit MAY BE SAVED in the day of the Lord Jesus." 1 Corinthians 5:1,5
To lose your salvation — makes God a LIAR
With all the PROMISES from God to KEEP you, to SAVE you, to PRESERVE you — to even suggest you could lose your salvation — is to call God a LIAR!
". . .he that BELIEVETH NOT GOD hath made him a LIAR; . . ." 1 John 5:10
Why do people doubt their salvation?
They trust in feelings rather than the word of God.
"He that trusteth in his own heart is a fool:. . ." Proverbs 28:26
They are confused by the simplicity of salvation.
"But I fear, lest by any means, as the serpent beguiled Eve through his subtlety, so your minds should be corrupted from THE SIMPLICITY that is in Christ." 2 Corinthians 11:3
They trust in tradition or church teachings rather than the word of God.
"Making the word of God of none effect through your TRADITION,. . ." Mark 7:13
They trust in their own righteousness.
". . . and all OUR RIGHTEOUSNESSES are as filthy rags;. . ." Isaiah 64:6
They misapply and misunderstand scriptures.
They misapply scriptures such as Matthew 24:13, Hebrews 10:26 to the church age of grace, when they doctrinally apply to the tribulation or the millenium. They have NEVER been saved.
"Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven;. . ." Matthew 7:21
