show scripture that says you can
There are several Scriptures that imply justification can be lost, but common sense alone should tell you that that justification can be lost. For example, if a believer loses his faith, is he still justified? No. There are thousands of atheists in the world who were once justified, believing Christians - now that they’re unbelieving atheists, do you think they’re still justified? No, of course they’re not. Loss of faith means loss of justification. Justification can also be lost due to committing “deadly” sins.
But since you asked for Scriptures which demonstrate that justification can be lost, here are a few:
"And the ones on the rock are those who, when they hear the word, receive it with joy, but these have no root, they believe for a while and in time of temptation fall away" (Luke 8:13).
Believers that are initially justified can fall away - meaning they lose their faith, thereby losing the justification that comes as a result of faith.
”There is sin which is deadly” (1John 5:16)
A “deadly” sin is sin that puts the believer’s hope of salvation at risk. If a believer is not saved and ends up in Hell, then obviously he lost his justification.
“Now the works of the flesh are plain: immorality, impurity, licentiousness, idolatry, sorcery, enmity, strife, jealousy, anger, selfishness, dissension, party spirit, envy, drunkenness, carousing and the like. I warn you, as I warned you before, that
those who do such things shall not inherit the kingdom of God” (Gal 5:19-21).
Paul warns believers that their sins can lead them to Hell - any believer who ends up in Hell has obviously lost his justification.
“Note then the kindness and severity of God: severity towards those who have fallen, but God’s kindness towards you, provided you continue in His kindness; otherwise you too will be cut off” (Romans 11:22).
A believer can be become one of “those who have fallen” and be “cut off”. So the justified can become un-justified, through loss of faith or committing “deadly” sins.
” For
it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit, and have tasted the good word of God and the powers of the age to come, if they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put
Him to an open shame. For the earth which drinks in the rain that often comes upon it, and bears herbs useful for those by whom it is cultivated, receives blessing from God; but if it bears thorns and briers,
it is rejected and near to being cursed, whose end
is to be burned” (Heb 6:4-8).
This passage describes believers who commit apostasy and are ultimately “burned” - in other words, they are justified believers who commit “deadly” sin and end up in Hell. If they were once justified, but end in Hell, then obviously they lost their justification.
