Why and for whom do you do the things you do? There was a time when I did most things for God and others. I hate having to look on human suffering and my spirit knows that it is not God's will that anyone should suffer. So I did it for them and for God.
But when you do it for others and exclude yourself, your motivation eventually will dissipate. Humanity, when given over to self-interest or to Satan, has an iron clad methodology for draining everything out of you. This blog post was previously titled, "Do it for Others." But I have arrived at the point at which I have to do it for myself only, in the manner that benefits God and myself. Only then can I gain the capacity and the motivation to do for others. If we don't love ourselves first, we won't have enough love to give to others.
So perhaps you too have been brought to a point where you no longer have the drive or the motivation to do for others. Perhaps it is because you have ignored self for too long. Jesus endured the cross not only to save humanity, but also to save himself and to inherit the kingdom that was promised. Before you begin to do for others, first secure your personal needs.
