I think being converted by hearing the gospel in the twinkling of the eye (under ten seconds)
The Eunuch like Philip had a desire as a member of the priesthood of believers to apply the ceremonial law as a shadow . So that he too like Phillip could plant the seed and water it with the doctrines of God in a living Hope Christ would apply it to the hearts of those who hear the call of faith. Away he went with his new tongue the gospel, preaching the good news.
1 Corinthians 3:6 I have planted, Apollos watered; but God gave the increase.
No man will be found with a self-righteousness edifying their own self.
I can agree with you. God did not care if two guys wanted to play with water if it made them feel happy. Just don't tell me it's doctrine for the Church of God to play with water.
