It's time to grow up in Christ... and help others do the same.
Colossians 2:6-7 says, "And now, just as you accepted Christ Jesus as your Lord, ... Let your roots grow down into him and draw up nourishment from him, so you will grow in faith, strong and vigorous in the truth you were taught. "
Don't you want that to be true for your life? Well, it isn't automatic. You need to be engaged and involved, pressing on to get to know God better and to align your thoughts and life with Him. It's not too late for you!
