Jn. 15:7 – If you abide in Me, and My words abide in you, ask whatever you wish, and it will be done for you.
Oneness, that is what our hearts are crying out for and that is what Jesus is describing through this powerful illustration of the Vine and the branches. He is the vine we are the branches. We are connected to Him, the life that He experiences He shares with us. His life is flowing in us and through us. In this verse the Lord describes the practical way we can flow with Him and allow this experience to deepen in us. Jesus is the Word of God, as we abide in His word we begin to experience the beauty of our union with Him. His word is in us, His word birthed us, His word enlivens us, His word is the very life of God in our souls. This is the source of our power in our prayers, Christ Himself is breathing His prayers in us by His Spirit and His word. Abide in His word and you will abide in Christ and His life. Here is how Andrew Murray describes this verse.
“If ye abide in me, and my words abide in you–This He gives as the equivalent of the other expression: “I in you. If my words abide in you”–that is, not only in meditation, in memory, in love, in faith–all these words enter into your will, your being, and constitute your life–if they transform your character into their own likeness, and you become and are what they speak and mean–ask what ye will; it shall be done unto you. Your words to God in prayer will be the fruit of Christ and His words living in you….If ye abide. Yes, Lord, the power to pray and the power to prevail must depend on this abiding in Thee. As Thou art the Vine, Thou art the divine Intercessor, who breathest Thy spirit in us. Oh, for grace to abide simply and wholly in Thee, and ask great things.”
So Jesus is taking us beyond memorization and mental acceptance, He is teaching us to take the word of God into the depths of our heart. Love His word, embrace His word, delight in His word, and your prayers become intertwined with His prayers. This is the place where we begin to bare fruit. The result; God is glorified and we are filled with joy.
