Joshua 11-12, Psalms 102, Acts 13
God is literally fighting the battles for the Isrealites in Joshua 11 and 12.
In Psalm 102 the Psalmist is in distress and pouring his heart out to God. The Psalmist is asking God to fight his battle for him. You see if God did it for the Israelites he can do it for anyone-including you today.
Act 13 Paul (Saul)and Barnabas are appointed by the Holy Spirit to go out to share the good news. Paul is an eloquent speaker and that made the Jewish leaders where jealous.
