I really recommend to be very careful with this Church.
Jesus set us free. We are not slaves. We need the faith that Jesus is our savior and obey HIS commandment: Love each other as He loves us.
Of course if you Love God, you want avoid sin, but it does not have to do anything with the clothes we wear or the music he hear. God sent Jesus to save the world, do you think he wants to curse people? That is a lie. He is the good sheperd. God is love and mercy. He has compassion and love for all of us. He wants us to have life and have it in abundance. Jesus wants us to have rivers of living water. How can a God that wants that for us also curse? Even we are called to bless and do not curse.
Everything you are saying about this Pastor's teachings remainds me the Pharisees, judging by the appereances and puting heavy loads over people shoulders.
