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. John 15:5

We are the branches; He is the Vine out of which we grow. Your life, and all your fruit-producing power lie in your union to Christ. You are not merely new-created, but you are created in Christ Jesus. It is not merely a change from a lower nature to a higher, but from separation from Christ to union with Him. What a wonderful thing that is-that you and I should not only be creatures in the world, but new creatures in Christ Jesus! Creatures we were in the first Adam; but our new-creatureship is in the second Adam. Beloved, if you are what you profess to be, you are one with Jesus by that vital union which cannot be dissolved; and good works follow upon that union. Joined to Jesus by faith in Him, love to Him, and imitation of Him, you walk in good works. Your creation to holiness is your creation in Christ Jesus. As you become one with the anointed Savior, His anointing ordains you to service, and His salvation leads you into obedience. There cannot but be fruit on that branch which is vitally joined to that fruitful stem, Christ Jesus, who did always those things which pleased the Father.

Our good works must flow from our union with Christ by virtue of our faith in Him. We depend upon Him to make us holy. We depend upon Him to keep us holy. We overcome sin by the blood of the Lamb. We reach after holiness by the constraining love of Jesus. ~ C.H. Spurgeon
