Why can’t we un- believe in the Lord?

Question:
Why can’t we un– believe in the Lord?

Answer:
John 10:28-30 tells us that the life that the Lord gives us when we trust ourselves to Him is “eternal.” So we can’t lose it, even if we wanted to. John 1:12 says that God makes us “sons of God” the moment we “believe” on Christ or “receive” Him, and when God does something it can not be changed. “I know that, whatsoever God doeth, it shall be forever: nothing can be put to it, nor any thing taken from it: and God doeth it, that men should fear before Him” (Ecclesiastes 3:14).
