This preaching by the great servant of the most high God, was alive and powerful the day it was preached it is still powerful even today, I believe it will be powerful until the Lord Jesus Christ come for his church. Glory to God amen.
However, Jesus told the disciples to wait (not by claiming and confessing the power in them) in Jerusalem to receive the power from on high eventhough they had already received the mandate to preach the gospel. TL Osborn never did any miracle before he experienced from Jesus eventhough he already preached the gospel before.
