It is those who claim we need not obey God and even condemn those who obey God who make a false separation between belief and obedience - let us not fall into the same error.
"With the heart man believeth unto righteousness" Ro 10
"This is the work of God: that ye believe on him whom he hath sent." Jn 6
"I will show thee my faith by my works." Ja 2
Belief is the body and works are the spirit - they only live as one.
