Just as Paul was not ignorant of the power of prayer and speaking in tongues, neither were the early Christians. The early Christians understood that they could not neglect prayer:
But we will give ourselves continually to prayer and the ministry of the word.
Giving yourself to long stretch of time praying in tongues will be a vital key to tapping the miraculous and moving in the glory of God.
We know that we are living in the last days and that the Lord’s return is imminently upon us.
And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
Acts2:4
