(John 8:17) "It is also written in your law, that the testimony of two men is true."
(2 Corinthians 13:1) "This is the third time I am coming to you. In the mouth of two or three witnesses shall every word be established."

9 ways God Speaks--
(2 Tim 3:16, Psalm 119:11, 105): This is the most clear and effective way of God’s communication with his people. If you want to know how things works perfectly, you need to read the manual. Bible is God’s manual for his people. But as in case with other manuals, we often ignore Bible. How often do we try everything else, but his words?
Through the inner still, small voice of Holy Spirit (Acts 11:12, Acts 13:2, Acts 16:6-7, 1 Kings 19:12, Isaiah 30:19-21)
Through the advice and counsel of men and women of God (Prov 12:15)
Through the Audible Voice of God (Acts 9:4-5)
Through Dreams (Matthew 1:20-21) – There are many instances in the bible, when God clearly communicates through dreams.
Through Visions (Acts 10:9-18)
Through Angels (Luke 1: 26-38) (Check out Angels and Demons: Bible Study)
