In these passages is the account of Jonathan, Saul’s son, confronting the Philistine garrison with only his armor bearer at his side. Jonathan demonstrated real Faith in God by his actions. He knew that God was able to defeat the enemy with few or with many soldiers. Jonathan defeated the Philistines because of his Faith in God..
Saul, on the other hand, was not aligned with God. He made foolish decisions, such as forbidding his soldiers to nourish themselves until the battle was over. Saul almost put Jonathan to death for violating this foolish edict.
Later we see that Jonathan became the future King David’s best friend. Jonathan trusted God. David trusted God. The Bible says, “Their souls were knit together.” I believe there is such a kinship between believers like David and Jonathan.
