Total yielding to God, submission to God selflessness, ability to work for God and do his will without looking back without having any regrets about God.
A true disciple should show a good example, and work in God's vain yard tirelessly without relenting and without soccumbing.
You won't say you are a true disciple without doing the necessary things you should do, just like in the bible peter and Paul Left everything they were doing just to follow God that's what descipleship means.
