25 Jesus answered them, “I told you, and you do not believe; the works that I do in My Father’s name, these testify of Me. 26 But you do not believe because you are not of My sheep. 27 My sheep hear My voice, and I know them, and they follow Me; John 10:25-30 (NASB) (Read verses 28-30 on the site)
God is Sovereign. That sovereignty is not partial. It is not subject to any conditions or forces outside of God. He has never nor will He ever relinquish any portion of His sovereignty. What He sets out to do, He does. What Men believe or refuse to believe about these truths changes nothing. Just because professing Christians cling to the fallacy that they are saved because they exercised their free will does not in any way diminish the truth from God’s Word that tells us the very opposite.
