8 And when they had ministered those same words which Jesus had spoken–nothing varying from the words which Jesus had spoken–behold, they knelt again and prayed to the Father in the name of Jesus.9 And they did pray for that which they most desired; and they desired that the Holy Ghost should be given unto them.
I admire the diligence of these disciples in ministering precisely the words of a Christ and neither more no less. I think these two verses are closely connected. It is precisely because they taught the words of Christ that they could with faith pray to have the Holy Ghost. If we deviate from Christ’s word, then we can in no way expect to have the Holy Ghost with us when we teach or testify.
