So, when the people saw the [miraculous] sign that Jesus had performed [i.e., the feeding of the large crowd with such a small amount of food], they said, “Truly, this is the prophet who was to come into the world.” [Note: This was probably a reference to the promise made in Deut. 18:15-19].
Every person who believes that Jesus is the Christ [i.e., God’s specially chosen one] has been [spiritually] conceived [and eventually born] by God. And everyone who [continually] loves God, who did the conceiving, also [must continually] love the person whom God has [spiritually] conceived.
And [in addition], we know that the Son of God has come [in a physical body, See 4:2] and has given us understanding, so that we can know the True One [i.e., God], and that we are in [fellowship with] the True One, even His Son Jesus Christ. This Son is the true God and eternal life.
As they [i.e., Philip, the Ethiopian eunuch and his attendants] traveled along they came to a certain [body of] water. The [Ethiopian] eunuch said, “Look, here is [a body of] water, why can’t I be immersed [right now]?”
and they said to the woman, “Now we believe, not just because of what you said, but because we have heard [it] for ourselves and know that this is truly the Savior of the world.”
