When people hear the good news that all their sins have been forgiven because of the cross of Jesus, something supernatural happens.
This is what happened in the book of Acts.
When Apostle Paul preached on forgiveness, healing miracles occurred as the people listened. The man who was lame from his mother's womb leapt up and walked for the first time in his life.
People in the church are looking for great power, but where is it found? The book of Acts declares that where there is great grace, there is great power!
