End results are up to God

1 Corinthians 3:6 I have planted, Apollos watered; but God gave the increase. When God leads us to witness and we don't see fruit from that particular labour, we can be assured that we at least planted a seed. Later on, we might not even be the first one that sees the fruit from the witness. God could have sent someone in the persons life to water and nurture that seed that may have been impossible to see. Either way the end result is up to God, because at the end of this verse it says but God gave the increase. This is the perfect picture of the first part of verse 9 in this chapter. It says for are laborers together with God. In verse 6 we see Paul planted, Apollos watered but God gave the increase. Both those things had to happen before any fruit was produced.  App: Today I will send an email to a friend back home and pray that whatever I say either plants a seed or waters a seed.
