These words are found in John 1:46 and John 4:29. The first reference was an invitation from Philip to Nathanael, and the second was an invitation from a Samaritan woman to her townspeople.
These simple words had such an impact on the lives of so many. Just look at the responses of Nathanael, “Rabbi, thou art the Son of God” (John 1:49) and “…and many of the Samaritans of that city believed on him for the saying of the woman, which testified, ‘Come see a man that told me all that I ever did.’” John 4:39.
Notice, Philip and the woman at the well had just met this Jesus. They had no formal training, and they did not present a plan of salvation…they just said, “Come and see.”
We can extend an invitation to anyone at anytime, by simply saying, “Come and see what God is doing.” We do not have to profess to know it all or to understand the mysteries of God.
When we say, “Come and see,” we loose the Holy Spirit to work his mighty work.
