In John 15, Jesus provides the imagery of Himself being the vine and the rest of us as the branches.
Joh 15:4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.
Joh 15:5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.
I don’t know how comforting this is. I think that we have this internal desire to want to go it on our own. We want to be independent, and we want to be self-sufficient, but here is Jesus Christ telling us that we cannot do anything outside of Him. In context, we are talking about a bearing fruit as a follower of Christ, so we certainly can do evil without Christ, but if we want to see these positive fruits coming out of our lives and in to places in the lives of people around us, then Jesus is telling us that it needs to come from Him.
I sometimes think that we want Christianity on our own terms. We want to do what we want to do; we want to see fruit when we want to see fruit. We need to abide in Christ. Like a branch draws life from the vine, we need to draw our life from Jesus Christ. We cannot draw that life from ourselves; it needs to come from someone beyond us.
I still like the idea of independence. I still like the idea of wanting to the master of my own fate at times, but that is not what we are called to do. We depend on Christ for everything, and without Him, we can really do nothing.
