Yeshua said: “I am the vine; you are the branches. Whoever lives in me and I in him, he it is that bears much fruit, for apart from me you can do nothing” (John 15:5). We cannot create the new birth by means of moral reformation, since the divine life is a miracle from above and not the result of human agency or aspiration (John 1:13; John 3:6). If we “live in” Yeshua we will bear fruit – our spiritual connection or “union” with him is sufficient for every good work, but only fruit that derives from the life of Messiah will abide (1 John 2:17). Good works are a necessary consequence of regeneration in Messiah, but by themselves they are insufficient and something more is needed (Matt. 7:21-23). Therefore the Scriptures point to the salvation of God and his grace as the efficient cause for the miracle of newness of life: “Not by works of righteousness which we have done, but according to his mercy he saved us…” (Titus 3:5); “for by grace are you saved through faith, and that not of yourselves (τοῦτο οὐκ ἐξ ὑμῶν), it is the gift of God” (Eph. 2:8); “so if it is by grace, it is no longer on the basis of works; otherwise grace would no longer be grace” (Rom. 11:6).
Grace and human effort are mutually exclusive when it comes to life from above: “It is the Spirit that gives life (τὸ πνεῦμά ἐστιν τὸ ζῳοποιοῦν); the flesh (i.e., human nature) is no help at all” (John 6:63). There is a new “center” of identity within the heart: “I is no longer I who live…” (Gal. 2:19-20). We do not appeal to God for mercy based on our best efforts, but like father Abraham we believe that God brings life to the dead. In short we believe that “salvation is of the LORD” (יְשׁוּעָתָה לַיהוָה), that is, that God justifies the ungodly and performs the inner work of salvation on our behalf and for our healing (see Rom. 4:1-5:2). As C.S. Lewis once said in this connection: “The Christian is in a different position from other people who are trying to be good. They hope, by being good, to please God if there is one; or — if they think there is not — at least they hope to deserve approval from good men. But the Christian thinks any good he does comes from the Christ-life inside him. He does not think God will love us because we are good, but that God will make us good because He loves us; just as the roof of a greenhouse does not attract the sun because it is bright, but becomes bright because the sun shines on it” (Mere Christianity). However we must not confuse cause and effect. The work of God is to believe in Yeshua (John 6:29) and we then learn to “work out” what God has “worked in” to our hearts by faith, as it says, “work out your own salvation with fear and trembling, for it is God who works in you, both to will and to work for his good pleasure” (Phil. 2:12-13). God who has performed a good work in you will “confirm you to the end blameless in the Day of our Messiah Yeshua” (1 Cor. 1:8; Jude 1:24-25).
