How do you get your answers?
Do you have any spirit life at all?
I'll assume your question is serious.
Jesus, being God, has innumerable means at His disposal. Among those more commonly experienced by His disciples are applications of relevant Scripture, promptings of the indwelling Holy Spirit, circumstances, counsel of other mature believers, pronouncements by those in authority, personal intervention by the Lord Himself, etc. All of these means and more are vividly illustrated in the Bible.
