By nature, we are sight-walkers, not faith-walkers. We tend to have confidence in that which we can see, that which we have known. We fear that which we can’t see and haven’t known.
Not only does Israel refuse to go into the land because of the giants-the Israelites want to return to Egypt! Do they not remember that they were slaves there? Do they not remember that they cried out in tears to God for deliverance from Egypt?
You can’t go back to your old life. There is nothing there but bondage. Your hope lies in following the Lord by faith. Walk forward.
