What is the basic responsibility of every Christian?

“Crucifying the flesh is basic responsibility of every Christian.
Why? Because God’s word says so! (Luke 9:23)
Crucifying the flesh is how one denies self and takes up his cross daily to follow Jesus." -Johnson and Pearl 

Luke 9:23 King James Version
“And He (Jesus) said to them all, If any man will come after Me, let him deny himself, and take up his cross daily, and follow Me."

Galatians 5:24 King James Version
“And they that are Christ’s have crucified the flesh with the affections and lusts."

“It is impossible for a Christian to stop sinning without crucifying the flesh. And “without a stop to sinning, it is impossible for a Christian to receive God’s promises, blessings, and power." -Johnson and Pearl

“Without crucifying the flesh the Christian will not be able to humble self, deny self, deeply repent, stop sinning, walk in holiness, get your prayers answered, and grow in hunger for God. " -Johnson and Pearl

“How important is it crucify the flesh? Without it the Christian cannot humble self, deny self, deeply repent, stop sinning, walk in holiness, get your prayers answered, and grow in hunger for God. And without humility, repentance, hunger, holiness, fasting and prayer, a person will not be able to receiving God’s blessings, promises, power, and revival.” -Johnson and Pearl
