Deut. 3, 4
Moses was prohibited from entering the Promised Land because he did not sanctify the Lord’s name at Meribah (by allowing God to produce water from the rock rather than Moses striking the rock). God gave him a look at the land from the top of Mt. Nebo near Pisgah. Moses then gave final instructions to the nation as they commenced to enter and take the land. They were to stay true and loyal to the Lord by following His Commands and refusing to worship the false gods of the inhabitants. If they did so, God promised to fight for them and give them the land.
When we take matters into our own hands and fight, we forsake God’s power and ability to give us His Kingdom. He will fight our battles as we pray and praise Him.
“Fear not, little flock; for it is your Father’s good pleasure to give you the kingdom.” -Jesus [Luke 12:32]
