John 15:4-5
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. 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.
Jesus Christ is the Word of God. When you abide in Christ, you abide in the Word and there is no telling how far you'll go. You produce much fruit this way.
He is the vine and you are the branch, there is a connection from you to Him. You need Him as much as He needs you to produce much, Hallelujah!
Therefore to abide in Christ is to abide in the Word. Stay in the Word, and watch you life move from one level of productivity and increase to another.
