"How great are his signs, how mighty his wonders! His kingdom is an everlasting kingdom, and his dominion endures from generation to generation."
Daniel 4:3 ESV
The Holy Spirit is alive and active and still performs miracles and will keep doing them from generation to generation.
There was a time in my life where I didn't believe that God could heal people until it was done in front of my eyes. A couple of pastors and I prayed for my Dad and he was healed on the way home after a concert. That's when I started to believe strongly and fully in the Holy Spirit. Have faith and believe what His word says, that he is still the same yesterday, today, and forever.
Lord Jesus I pray you will open my eyes to things unseen and ears to things unheard. Holy Spirit I pray that you will give me faith to believe in your healing power and that you still heal today. In Jesus' name, Amen.
