The Philistines are very worried. They have got their God with them.
When Christians play the world at their own game, they may well find they are not as good as the world is at doing what they do. The church of God has weapons of its own which are invincible while they are handled in the right way. But for them to be effective, God’s people must be obedient to him from their hearts, and going about his work in the way that he has commanded. It is a tragedy for the church to start imitating the world in order to advance the gospel, for instance through drama and music and entertainment, instead of serious proclamation of the word of God.
