Paul gives the balanced approach to praying in 1Cor 14v15:
"What is the conclusion then? I will pray with the spirit, and I will also pray with the understanding. I will sing with the spirit, and I will also sing with the understanding."
He teaches that we should pray in tongues and with the mind as well as sing in tongues and using the mind, and certainly this pattern worked for Paul (and no doubt ALL the Christians of the Churches set up through him by the Lord followed his example)! Rom 1v9, 15v18-21, 1Cor 14v18, 2Cor 12v11,12, 1Thess 5v17.
Acts 2v15-21,38,39 (with 1Cor 12v7-11,28, Eph 4v7-16), teaches that spiritual gifts and spiritual ministries are set in the Church throughout the WHOLE of the age of Grace, right up the the Second Coming of the Lord Jesus!
Is Paul's example, which he no doubt received from the Lord Jesus, not good enough for us today? Gal 1v12.
