2CO 6:1 As God's fellow workers we urge you not to receive God's grace in vain. 2 For he says,
"In the time of my favor I heard you,
and in the day of salvation I helped you."
I tell you, now is the time of God's favor, now is the day of salvation.
Even Christ Jesus did not heal the whole world when he first arrived; everyone that he healed has to believe in himself in order for Christ to reach to him to heal him. For Christ Jesus was still a mortal being and he couldn’t infringe on the choices of Man.
