1 Timothy 3:1-2
Here is a trustworthy saying: Whoever aspires to be an overseer desires a noble task. 2 Now the overseer is to be above reproach, faithful to his wife, temperate, self-controlled
1 Corinthians 9:24-27
Do you not know that in a race all the runners run, but only one gets the prize? Run in such a way as to get the prize. 25 Everyone who competes in the games goes into strict training [literally, “exercises self-control in all things”]. They do it to get a crown that will not last, but we do it to get a crown that will last forever. 26 Therefore I do not run like someone running aimlessly; I do not fight like a boxer beating the air. 27 No, I strike a blow to my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize.
For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever you want.
Then the Lord said to Cain, “Why are you angry? Why is your face downcast? 7 If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must rule over it.”
But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, 23 gentleness and self-control.
