Brothers, do not be children in your thinking. Be infants in evil, but in your thinking be mature. 1 Corinthians 14:20.
“Maturing means you have begun to see that God is in control of this world. He is working out purposes that you do not always understand, but you accept it. He will take you through the deep water, not drown you in it. Maturity means you are learning to trust. It also means to be satisfied more with giving than receiving.” – J.I.Packer.
