Byblos, faith with out works is dead james tells us.
Our spiritual act of worship is to present ourselves to God, not hearts, not our feet, our entire body that includes the mind, Jesus is not just the lord of hearts, He is Lord of ALL. Great faith? great faith in WHAT? Muslims have great faith, so do mormons and jehovah wittnesses, that doesnt mean that they are going to heaven. Romans 3:9-20 make it absoluely clear that no one is righteous and we are not going to heave. it is by grace alone we are saved yes, but God did not tell the disciples to Go out into the church and sing some songs. He said go out into the world and make disciples (a disciple is someone who studies what the master has tuaght) not church goers and attenders who listen to ONE disciple/teacher. Paul and Peter both tell us commonly in their epistles to study Gods word?
DO you have the sword of the spirit? what good is your shield of faith if you do not have the sword? or the belt of truth, are your feet fitted with the gospel of peace? do you even know where this is referrenced from? most of it is a direct quote.
How can you know God if you only listen to one man teach, no, knowning God is a personal relationship you have by studing His word and growing with Him in a daily walk and conversation.
