If you want to know if you are growing as a Christian ask yourself the question, "Am I more dependant on Jesus than I was yesterday?"
Jesus said, "Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me. I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing." John 15:4-5
