Charles Spurgeon Commentary John 1:39-42

"He saith unto them, Come, and ye shall see. They came therefore and saw where he abode; and they abode with him that day: it was about the tenth hour. One of the two that heard John [speak], and followed him, was Andrew, Simon Peter`s brother. He findeth first his own brother Simon, and saith unto him, We have found the Messiah (which is, being interpreted, Christ). He brought him unto Jesus. Jesus looked upon him, and said, Thou art Simon the son of John: thou shalt be called Cephas (which is by interpretation, Peter)." — John 1:39-42 (ASV)

They came and saw where he dwelt, and abode with him that day: for it was about the tenth hour. One of the two which heard John speak, and followed him, was Andrew, Simon Peter's brother.

He first findeth his own brother Simon, and saith unto him, We have found the Messias, which is, being interpreted, the Christ. And he brought him to Jesus.

This is how the kingdom began to grow – by individual effort.

Andrew findeth Simon: one convert must bring another: and he brought him to Jesus.
