- Who is active in baptism? Baptism is primarily an act done to the baptised by God through the minister, not an act done by the baptised. In your baptism you are primarily a receiver and not a giver.
- What is the act? It is the visible, physical and verbal promise declared to the baptised that Jesus Christ died and rose for the forgiveness of their sins so they now have a new identity in Christ.
- When should someone be baptised? The promise in baptism must be received by faith to be of any benefit but that faith may come later. Faith is always preceded and created by the declared promise, so it is natural for infants to be baptised even if they do not yet believe. Because the declared promise is the cause of faith, it actually is more logical for baptism to precede first faith.
Q: How does baptism relate to preaching? A: Both are declarations of the word of promise, but baptism has a unique role as the distinctly personalised and embodied promise. We need the concreteness that baptism and the Lord's Supper provide and preaching doesn't.
Q: Why do adults have faith before being baptised? A: Faith may be present in the baptised beforehand, but only because they received the promise in a purely verbal form earlier (e.g. through preaching). Faith is not a prerequisite of baptism so as soon as someone is willing to be baptised then baptise them straight away without question. No need to test their fruits, because the promise is how those fruits are created.
I think, adult-only baptism is a symptom of getting the who? and what? questions wrong. I'm sorry for the lack of proof texts, but a quick look through the NT texts on baptism should make the first two answers clear, and the third then just follows from that.
