Many in false religion believe that the natural man can put faith in Christ in regards to Salvation, but that is a lie, Faith is a Gift bestowed upon redeemed man, and comes from his Head and Saviour Jesus Christ, Acts 5:31 31 Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance/faith to Israel, and forgiveness of sins. Repentance and Faith are the same blessing, identical twins. The word repentance is the greek word metanoia: repentance, a change of mind, change in the inner man. Its a change of mind in turning from dead works to Faith in God Heb 6:1 Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God, Paul exhorted what in Acts 20:21 21 Testifying both to the Jews, and also to the Greeks, repentance toward God, and faith toward our Lord Jesus Christ. Repentance from God and or Christ persuades the Mind which gives birth to Faith ! Man in Adam did not have Faith in Christ because before the fall man had no need for it, being that Faith in Christ is connected with Christ as the Saviour from sin, it[Faith/Repentance] was not in man naturally by creation, it was a Gift stored in Christ for Redemptive Purposes, part of that fulness that in Him dwelled Col 1:18-19 18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence. 19 For it pleased the Father that in him should all fulness dwell; And those of us who were Chosen in Him who is the head of the Church His Body, we receive from His fulness grace for grace Jn 1:16 16 And of his fulness have all we received, and grace for grace. Thats how we receive both Faith and Repentance, out of His Fulness as He is Our risen Saviour and Head Acts 5:31 31 Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance to Israel, and forgiveness of sins. The word Prince is equivalent to the word Head in Col 1:18 18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence. The word head kephalé: (a) the head, (b) met: a corner stone, uniting two walls; head, ruler, lord. anything supreme, chief, prominent; of persons, master, lord And the word Prince in Acts 5:31 is the word archégos: originator, author, founder, prince, leader the chief leader, prince: So Both words define the preeminence of Christ over His Body, in Acts 5:31 His Body is Israel, in Col 1:18 His Body is called the Church ! And the point is this, only as members of His Body/Israel do we receive Faith/ Repentance to believe in Him, its not in man by nature, hence Jesus says Jn 6:64-65 64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him. 65 And he said, Therefore said I unto you, that no man can come unto me[naturally speaking], except it were given[redemptively] unto him of my Father. Its given to us redemptively when He gave us His Son in whom all redemptive fulness dwells, and if we be Christ's Church / Israel, we receive of His fulness, Grace for Grace Jn 1:16 !
