They are generous to a fault, never operating on the idea of limited resources, rather, as Christians, they operate on the belief in life abundant. They believe that the Good News that Christ defeats death and all evil is true. Now, how do we appropriate that kind of belief for ourselves. The way to sound belief lies in action. Christian action is a form of prayer.
Belief comes with the kinds of prayer that are manifest in action.
Live the life of one for whom the Good News of Christ is the ultimate truth. Live the life that assumes that in the end all will be well, the life that is underlain by the fact that in Christ no catastrophe is ultimate, no evil is final, and no death is forever and in time you will absorb the facts of that Good News. Christ does not ask that of you. Christian belief is like teaching. Teach a subject and you will know it far better than you ever could, just studying that subject.
