Christian Worship is primarily about worshipping God for who He is and what He has done for sinners like us. If it is entirely about Him, then we are to worship in a way that God prescribes and instructs. The Holy Spirit enables us to worship God in a way that is acceptable to Him.
In Christianity, the root of all sexual sins is a selfish obsession to ones own desires and gratification. In one sense, Self-love is the root of all sexual immorality. So the way to fight sexual sins in our relationships in the church and in our marriages is to learn to love others and understand what it means to love them. Sacrificial love towards our spouse is the way to fight sexual temptation.
