We have observed that there are doctrines in the way of worship of God, so there are different methods of service which God expects from us.
We cannot deny the way that God wants us to serve Him. We have to choose our own way and then choose what we expect from Him. God is not answerable to any of us, so we are answerable to God.
He is our God and we are just His subjects. Those who are His followers or worshipers are most ready to keep obeying the will of God.
God has His ways and manner in which He wants us to worship Him. So when the Lord Jesus Christ came to the earth, God offered Himself to join the baptism and wants us to be baptized. So that was humility.
That humility was always there, though He was a creator but He submitted. He was willing to learn and serve people. That's what God has always been teaching us, to obsess that and it's not so that we are bigger than His principle.
We should always live with pride but He wants us to be humble and live a life of humility. So baptism is an important aspect of teaching Jesus Christ. Which you must obey as a Christian.
We have our duty to be baptized. There's no doubt of being happy in God that to obey his commandments. Obedience is better than sacrifice. Instead of to break and back that, rebel on that we always want to obey his commandment which is given to us.
