You need to recognize who God is
Joshua 4: 24He did this so all the nations of the earth might know that the LORD’s hand is powerful, and so you might fear the LORD your God forever.
God does miracles and great works so we would know who the one true God of the universe is. People think God is weak because are weak. We need to stop being these faltering, timid disciples and start men and women who are walking in the power and presence of the Lord. Then the world will begin to take notice who the true God is. God has always used people to show Himself strong and today is no different. Will I be the one to show the world the power of God or will I be like everyone else with no authority and no annointing? This will be determined by how much I walk in His plans and in His word.
