If you need a miracle in your life, then study miracles. Read about miracles in the Bible and see what God has done. How much faith did the people have? How much did God do? If God is the same yesterday, today, and forever, then He’s ready to do something miraculous today.
Reading about miracles and hearing testimonies of what God has done in the past, builds your faith. Set your expectations that God will do something that defies the laws of physics or circumstance. God moves for people who are looking for Him to move.
Seeing a miracle should be common place for us. And these signs will follow those who believe: In My name they will cast out demons, they will speak with new tongues, they will take up serpents, and if they drink anything deadly, it will by no means hurt them, they will lay hands on the sick, and they will recover. (Mk, 16:17-18)
If you are a believer, then miracles are to be expected. God said so. Just believe that He’s still the God who parted the Red Sea and raised Jesus from the dead. Then give Him all the praise when He does what you asked Him to do.
