Scriptures clearly teach that believers can commit apostasy( John 15:1-6,Romans 11:18-23, Hebrews 6:4-8,10:26-39,2 Peter 2:20-22). I have examined Hebrews 10:39 and amply demonstrated that contrary to Unconditional Eternal Security heretics, the verse teaches the opposite; believers can turn into apostates and objects of the wrath of God. As I said, this is an uncomfortable truth, but truth is never based on comfort. We must follow it wherever it leads us. The subject portion is important because it records the very words of our Master addressing his disciples. John 15:1-6 (KJV) I am the true vine, and my Father is the husbandman. 2 Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit. 3 Now ye are clean through the word which I have spoken unto you. 4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me. 5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. 6 If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.
