Selfishness, stinginess is an especially serious sin. The Bible implies this when it says, “The love of money is the root of all evils” (1 Tim. 6: 10).
It is clear that all who have an exaggerated love of earthly things will be excluded from the Kingdom of God, for it is written that they will not “inherit the kingdom of God” (1 Cor. 6: 10 and see Eph. 5: 5). Yes, selfishness, like covetousness, is idolatry. “On account of these the wrath of God is coming upon the sons of disobedience” (Col. 3: 5b, 6).
Because the selfish have such a serious punishment awaiting them, and the wrath of God is upon them now, we have to become free from stinginess at all costs. It is more or less in all people, even if it is not so obvious in some. It can appear with seemingly harmless symptoms. “Thriftiness”, or “smart planning” can be possible camouflages.
Selfishness reveals its true face when it is hard for us to give away something. That can happen in many areas, depending upon what our heart is especially attached to. So a stingy person will sometimes “wallow” in his possessions, not wanting to give them away, until he almost drowns in them. Often he refuses to give to those who ask, and he will never part with any money or possessions voluntarily. He is bound to the transient things of this earth. But he does not realize that he is also bound to the prince of this world, to Satan. He has become his servant here and one day will not inherit the Kingdom of God, even if he did seem to believe in Jesus on earth.
