Actually Jesus is called God in the New Testament, several times, and by those who knew Him best:
Paul called Jesus the great God and Saviour. Titus 2:13
Peter writes our God and saviour, Jesus Christ. 2 Peter 1:1
Thomas addresses Jesus as My Lord and my God! John 20:28
John called the Word/Jesus, God. John 1:1
To me the most convincing proofs of Jesus deity is found by comparing certain scriptures in the Old Testament that clear talk about YHWH (Jehovah) often translated as LORD (all capitals), with scriptures that clearly talk about Jesus:
For instance, in Isaiah 40:3 it speaks about preparing the way for the LORD (Yahweh). When we compare this verse with Mark 1:3 we readily see that it is Jesus who is the LORD and had the way prepared for him by John the Baptist.
In Joel 2:32 it says that whoever calls upon the Name of the LORD (Yahweh) will be saved. This verse is reiterated by Peter in Acts 2:21, and Paul in Romans 10:13. Both apostles are clearly referring to Jesus as the LORD.
In Isaiah 6:1-10 we read about the marvellous vision that Isaiah had revealing the glory of the LORD (Yahweh). John tells us in John 12:40&41 that this vision revealed the Glory of Jesus.
In Isaiah 44:6 the LORD (Yahweh) refers to himself as the first and the last. )Alpha and Omega) This title is used again Revelation 1:8 & especially verse17 by Jesus
In Zechariah 12:10 the LORD (Yahweh) is saying that “they will look on Me whom they have pierced.“ This is obviously Jesus (the second person of the Trinity) speaking. (Psalm 22:16; John 19:34) This passage from Zechariah appears again in Revelation and is clearly about Jesus Christ.
Check these scriptures out for yourself and draw your own conclusions with an open mind.
