John 6:35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.

In order to "cometh" to Christ, a person must be drawn (John 6:44) of God, which is the same as being translated (Colossians 1:13). This is can only be accomplished by the Father (John 6:65). When the person is drawn, he is translated from the power and authority of darkness to the power and authority of Christ. Thus, the person is delivered to Christ (John 6:37 & 39). At the same time an adoption occurs and the person is received of the Father as a child (Hebrews 12:6). This is salvation by grace without works. It is referred to by Paul as the washing of regeneration (Titus 3:5), or more commonly today as simply regeneration. Therefore, those who only eat the flesh of the Son of Man or eat the bread of Life (John 6:50, 51, 57, 58), without also drinking His blood, will live forever, as opposed to possessing eternal life.

Of those who are delivered to Christ, having been regenerated and adopted as children, those who freely chose to believe in Him, will, by faith, partake in the drinking of His blood. In doing so, they will receive the earnest of their inheritance, which is the Holy Spirit (Ephesians 1:14, 2 Corinthians 1:22, 2 Corinthians 5:5), and obtain the immediate possession of eternal life (John 6:40, 47, 53, 54, 68).
