God of truth is a name of God that expresses His faithfulness. A series of related Hebrew words (’emet, ’amen, ’emunah) carry similar meaning and are part of several related names of God. The word ’amen is where we get our word “Amen.” Jesus used it to indicate assurance and certainty at the end of some statements (Matt. 5:18, 26). Jesus is Himself the Amen (Rev. 3:14; 19:11; and see 2 Cor. 1:20). Interestingly, Rev. 3:14 goes on to call Him faithful and true, which captures the underlying meaning of “Amen.” Jesus called the Holy Spirit the Spirit of Truth.
