The modern church is impotent because they don't know God. God on the other hand is omnipotent.
The Baptist teach that there are no modern apostles because apostles are taught by Jesus. Of course that definition is biblically incorrect an apostle receives the revelation of Jesus Christ according to Matthew 16:18 and Matthew 11:27 and in Luke 24 the 2 disciples on their way to Emmaus were disciples not apostles.
Get out of the church they don't know God.
