Jesus is God ?

Is Jesus being a real God? Of course, according to the Holy Bible, New Testament John 3: 31 to 36:" He who comes from above is above all; he who is of the earth is earthly and speaks of the earth. He who comes from heaven is above all." And what He has seen and heard, that He testifies; and no one receives His testimony. " He who has received His testimony has certified that God is true. " For He whom God has sent speaks the words of God, for God does not give the spirit by measure."' The father loves the Son, and has given all things into His hand."' He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him." Yip

Jesus is said to be the incarnation of God, so meaning the origins by and of God.

There are many names to call (or being written) Jesus during his time living among us, thus it becomes confusing if we think in terms of human nature or biologically relationship. For example, God spoke during Jesus' baptism that “You are my one dear Son; in you I take great delight.” (NET) or “You are my Son, whom I love; with you I am well pleased.” (NIV). So people argue that since God (from heaven) spoke to him as being “his Son”, Jesus cannot be the same God. However, Jesus spoke of himself as “Son of Man” throughout his life (instead of claiming to be the Son of God) with us to show us that the expression really mean “He is truly Man (human)” and at the end He represents mankind as the sacrificial lamb to God for remission of sin. This is just a simple and direct rhetorical or literary answer on this question only by studying the words or expressions without going into theological or biblical scripture justification or deduction about what God is or composes of.

Still, if you wish to study the theological arguments to proof or justify why or how Jesus is God, I’m sure you just need to search and found thousands of writing about it. However, if it is about your faith in Jesus, I would suggest you ask a reverse question for yourself:
What is the effect on your faith (say with God) if Jesus is not God?

He indeed is one of the three Gods in Christianity.
