Beyond the surface.

Psalms 44:3 (KJV) For they got not the land in possession by their own sword, neither did their own arm save them: but thy right hand, and thine arm, and the light of thy countenance, because thou hadst a favour unto them.

If you take this, literally, it sounds like Israel simply walked into the promised land, and it was delivered to them. If you read the story that is being referred to they had to fight for everything they got. The point is that ultimately it was God’s hand that brought victory not their own personal efforts.

So?  We are expected to follow in obedience and act on God's direction. God promises much but he also demands obedience.
