Along the line in ministry, it is possible for one to drift from the way to do things our away and not the way of God. Although one may point out many reasons why this may so happen, it often boils down to the lifting up of our hearts- pride or the drowning of our spirits- depression.
Seeing some level of success, being hailed by the people and being blessed financially can especially fuel the pride of the minister of God and cause Him to 'misbehave'. The opposite works in the same way. When nothing seems to happen in the ministry over a period of time and all you get is problems over problems, one can easily begin to drift away from the right ways of God.
Although these fueling agents of pride and depression are almost bound to happen, the minister must shield himself from them getting into His head and subsequently his heart. To do so, we can learn something significant from Apostle Paul in 2 Cor 4:2 and that is to see the ministry as a mercy shown us by God and not our entitlement.
2 Corinthians 4:1 (KJV) Therefore seeing we have this ministry, as we have received mercy, we faint not;
How can you get tired, faint or give up on a thing that you didn't deserve in the first place? How can you take for granted an assignment you were called unto that you were originally not qualified. The moment you understand that, God actually was favouring you by allowing into the ministry, you will never get complacent with.
Like the Apostle Paul, let's not faint, but rather let's renounce the hidden things of dishonesty, not walking in craftiness, nor handling the work of God deceitfully. But by manifestation of the truth commending ourselves to every man's conscience in the sight of God- 2 Cor 4:1-2
