God expects you to get your doctrine from the whole of scripture.
If the Bible were one verse, every doctrine of the Bible would not fit into that one verse.
So, sometimes God speaks of certain doctrines in specific verses; and expects you to get other doctrines from other verses.
Do a search on the word "baptize / baptized / baptism" and you may get a concise understanding of "the doctrine of baptisms" (Hebrews 6:1-3).
You may not get a doctrine about baptism from a verse that speaks about faith.
While there are a few verses that speak of both things, singular verses do not have enough room to speak of both doctrines for the most part.
