Kill someone else's Giant

2 Sam 21:15  … and David waxed faint. 16And Ishbi–benob, which was of the sons of the giant, the weight of whose spear weighed three hundred shekels of brass in weight, he being girded with a new sword, thought to have slain David. 17But Abishai the son of Zeruiah succoured him, and smote the Philistine, and killed him…

In this story we find David, fainting and getting tired. He is almost killed by a giant, but Abishai saved him by killing the giant. This he did because David had showed him it was possible to kill Giants. When David killed Goliath, he was killing someone else’s Giant. Goliath was not his problem. It was King Saul’s problem. It was the army’s problem. No one expected anything from David. He could have gone home, without anyone thinking he did something wrong. But he made it into his problem, and his issue. He killed someone else’s Giant. Because of that, at the end of his life, someone else is killing his giant.
If you help killing others Giants, and help others in their crisis, then someone else will come to your rescue when you have your crises. If you help pray for others cancer, and others family problems wit faith and passion, others will pray for you and help you when you get sick or need a miracle.
