Galatians 1:6
I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel;
Titus 1:15-16
To the pure, all things are pure; but to those who are defiled and unbelieving, nothing is pure, but both their mind and their conscience are defiled. They profess to know God, but by their deeds they deny Him, being detestable and disobedient and worthless for any good deed.
Hebrews 3:12
Take care, brethren, that there not be in any one of you an evil, unbelieving heart that falls away from the living God.
Hebrews 5:9
And having been made perfect, He became to all those who obey Him the source of eternal salvation,
Hebrews 6:4-6
For in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit, and have tasted the good word of God and the powers of the age to come, and then have fallen away, it is impossible to renew them again to repentance, since they again crucify to themselves the Son of God and put Him to open shame.
Hebrews 7:25
Therefore He is able also to save forever those who draw near to God through Him, since He always lives to make intercession for them.
Hebrews 9:15
For this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the transgressions that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance.
Hebrews 10:10, 14, 26-29, 36, 39
10 By this will we have been sanctified through the offering of the body of Jesus Christ once for all.
14 For by one offering He has perfected for all time those who are sanctified.
26 For if we go on sinning willfully after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but a terrifying expectation of judgment and the fury of a fire which will consume the adversaries. Anyone who has set aside the Law of Moses dies without mercy on the testimony of two or three witnesses. How much severer punishment do you think he will deserve who has trampled under foot the Son of God, and has regarded as unclean the blood of the covenant by which he was sanctified, and has insulted the Spirit of grace?
36 For you have need of endurance, so that when you have done the will of God, you may receive what was promised.
39 But we are not of those who shrink back to destruction, but of those who have faith to the preserving of the soul.
Hebrews 12:17
For you know that even afterwards, when he desired to inherit the blessing, he was rejected, for he found no place for repentance, though he sought for it with tears.
Hebrews 13:5
Make sure that your character is free from the love of money, being content with what you have; for He Himself has said, “I will never desert you, nor will I ever forsake you,”
James 1:6-8
But he must ask in faith without any doubting, for the one who doubts is like the surf of the sea, driven and tossed by the wind. For that man ought not to expect that he will receive anything from the Lord, being a double-minded man, unstable in all his ways.
James 2:17
Even so faith, if it has no works, is dead, being by itself.
1 Peter 1:4-5
to obtain an inheritance which is imperishable and undefiled and will not fade away, reserved in heaven for you, who are protected by the power of God through faith for a salvation ready to be revealed in the last time.
2 Peter 1:9
For he who lacks these qualities is blind or short-sighted, having forgotten his purification from his former sins.
2 Peter 2:20-22
For if, after they have escaped the defilements of the world by the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and are overcome, the last state has become worse for them than the first. For it would be better for them not to have known the way of righteousness, than having known it, to turn away from the holy commandment handed on to them. It has happened to them according to the true proverb, “A dog returns to its own vomit,” and, “A sow, after washing, returns to wallowing in the mire.”
1 John 1:6-7
If we say that we have fellowship with Him and yet walk in the darkness, we lie and do not practice the truth; but if we walk in the Light as He Himself is in the Light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin.
1 John 2:3-6
By this we know that we have come to know Him, if we keep His commandments. The one who says, “I have come to know Him,” and does not keep His commandments, is a liar, and the truth is not in him; but whoever keeps His word, in him the love of God has truly been perfected. By this we know that we are in Him: the one who says he abides in Him ought himself to walk in the same manner as He walked.
1 John 3:6-9
No one who abides in Him sins; no one who sins has seen Him or knows Him. Little children, make sure no one deceives you; the one who practices righteousness is righteous, just as He is righteous; the one who practices sin is of the devil; for the devil has sinned from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil. No one who is born of God practices sin, because His seed abides in him; and he cannot sin, because he is born of God.
1 John 4:15-18
Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him. By this, love is perfected with us, so that we may have confidence in the day of judgment; because as He is, so also are we in this world. There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love.
1 John 5:16-18
If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this. All unrighteousness is sin, and there is a sin not leading to death.
We know that no one who is born of God sins; but He who was born of God keeps him, and the evil one does not touch him.
