It would be cruel and insensitive to criticize a toddler child who is learning to walk when he stumbles. The normal approach is to cheer him on by saying something like, "'Atta boy! You can do it. Come on."
Why do we imagine that God is less compassionate and sensitive to human development than we are? He wants us to walk in faith and come to Him. When we stumble and fall into sin, He doesn't grind us down with condemnation. If we only have the will to try to please Him He will pick us up and say, "'Atta boy! You can do it. Come on"
