Jesus said God is the only one who is good. He also said that we must "be perfect, as your heavenly Father is perfect" (Matthew 5:48).
"Beloved, do not imitate what is evil, but what is good. The one who does good is of God; the one who does evil has not seen God." 3 John 1:11
"For by grace are you saved through faith, and that not of yourselves, it is the gift of God."
" ... There is only One who is good; but if you wish to enter into life, keep the commandments." Matthew 19:17
Galatians 3:24 states, "The law was put in charge to lead us to Christ that we might be justified by faith."
Faithfulness...one of the fruits of the Spirit. Child like faith opens the door but growing into mature Christians is what makes life good and fruitful.
