6 And now, just as you accepted Christ Jesus as your Lord, you must continue to follow him. 7 Let your roots grow down into him, and let your lives be built on him.
How do we grow? Not by programs or self-help books, diets, plans or methods but by drawing up nourishment from God. These methods may seem like they will change us and they probably will change our physical man but they have nothing to do with our inward growth in God. We grow in God as we get our nourishment from Him. We grow as God nourishes us as our roots grow down into Him and our lives built in him. Just like a tree draws its nourishment from beneath the soil. Its roots digging deeper until it finds the water then it draws it up to nourish the tree. So we draw up nourishment from the Holy Spirit. Jesus said whoever drinks the water He gives would never be thirsty. We drink him in and find our nourishment from Him. He supplies us and we grow as we draw our nourishment from Him.
