“It is a terrifying thing to fall into the hands of the living God.”
God made man and woman with free will, with option to obey or disobey God. He wants an intimate, personal relationship with us and not with robots. He made us like this so that we may choose to love and worship Him. Before the fall, we were in neutral gear, neither bias towards good or evil but after the fall, we have a tendency towards sin. That’s why we do what we ought not to do.
In John 3:17,18 it is written, “For God did not send his Son into the world to condemn the world, but to save the world through him. Whoever believes in him is not condemned, but whoever does not believe stands condemned already because he has not believed in the name of God's one and only Son.”
