John 1:35-39 — Again the next day after John stood, and two of his disciples.
And looking upon Jesus as He walked, he saith, Behold the Lamb of God!
And the two disciples heard him speak, and they followed Jesus.
Then Jesus turned, and saw them following, and saith unto them, What seek ye? They said unto Him, Rabbi, (which is to say, being interpreted, Master,) where dwellest thou?
He saith unto them, Come and see. They came and saw where He dwelt, and abode with Him that day: for it was about the tenth hour.
John the Baptist's ministry was to point people to Christ.
two disciples — Andrew and, probably John, the author of the book.
Andrew and John were disciples of John the Baptist who promised to show them the Messiah. They followed him until he did just that.
Rabbi — John interprets the title for his Greek readers
Where dwellest Thou? — they sought fellowship.
Come — Christ's first recorded words in John. All that the Father giveth Me shall come to Me; and him that cometh to Me I will in no wise cast out (John 6:37). Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by Me (John 14:6).
tenth hour = four p.m.
This is the final recorded time John the Baptist saw Christ. His ministry was decreasing as Christ's began.
John 1:35-42 tells of the disciples' conversion. Mark 1:16-20, occurring later, is their call to service (which was to Israel and isn't the focus of John's gospel).
Four methods of converstion — 1) Andrew and John heard a preacher; 2) Peter was told by his brother; 3) Philip was sought out directly by Christ; 4) Nathanael heard from a friend.
