Jesus is both the Son of God, and God, and the Son of Man. The Christian Trinity is about God as one God in three parts -- God the Father, Jesus Christ God's Son, and God's Holy Spirit. Jesus was born of Mary, a human, and so Son of Man. Jesus' Father who birthed Him was God's Holy Spirit, and so Jesus is God's Son. And Jesus is God of the Trinity too.
Jesus told parables about Himself being the Messiah, God, Son. Also, He was killed because Jesus said He was King of the Jews, God's Son. And, here He is talking about Himself being greater that the temple --
The Holy Bible
Matthew 12:5-7
"5 And haven’t you read in the law of Moses that the priests on duty in the Temple may work on the Sabbath? 6 I tell you, there is one here who is even greater than the Temple! 7 But you would not have condemned my innocent disciples if you knew the meaning of this Scripture: ‘I want you to show mercy, not offer sacrifices."
Read the book of Hebrews about who Jesus is and was -- God the Father has given Jesus Christ all authority on heaven and earth and He will come again to judge the living and the dead.
This is how to know God.-- the basic Christian message and prayer --- you need to accept God's Son, Jesus Christ, into your life to be a born again Christian and follow God's ways so you can receive God's guidance in your life and get to heaven after you die. Knowing God can transform your life. When you know God, then pray about your life, God can help you live a better life. As God is love, life is primarily about love and relationships in order to have a rich and full life. Also, you need to know God's Son, Jesus Christ, in your life as your Lord and Savior as Jesus died on the cross as payment for our sins. Having Him with you will give you God's blessing and forgiveness, as you live God's way. Not following God leads to hell, eternal suffering. Instead, there is an important prayer to pray to become a born again Christian. This prayer should be said with faith in God and a sincere heart:
"Dear God, I know that I am a sinful person and I don't want to be like this anymore. I know that Jesus Christ died on the cross as payment for our sins, and I want to accept Jesus Christ into my life as my Lord and Savior so I can receive God's forgiveness, guidance, and go to heaven someday. Thank you, dear God, for your mercy and guidance; in Jesus' name. Amen."
This prayer can take you to a new place in your relationship with God and transform your life. After saying this prayer, you should check out a Christian church, like Baptist or Lutheran. The church can get you baptized and prayed for, and you can pray for yourself daily. Also, get into their Bible study group so you can learn more about God, Jesus, and God's will for your life. The Bible is God's instruction book about how to live a God-honoring life so you can go to heaven after you die. Ways to stay connected to God's path include loving God and Jesus Christ, obeying God's ways, daily Bible reading, daily prayer for yourself and others, getting to church, having your church prayer group and/or pastor pray for you, fasting with prayer for a higher level of prayer, getting with other Christians and doing a Bible study, singing hymns to God, taking communion with the church, helping and loving others, expressing your gratitude to God for His help in your life by telling others of your progress and helping them draw closer to God too, tithing, volunteering at church. God guide your life.
