Pray in the Spirit at all times, with every kind of prayer and petition. To this end, stay alert with all perseverance in your prayers for all the saints.
What does it mean to pray in the Spirit? Many teach that to pray in the Spirit means to pray in tongues...or a heavenly language. There are two problems with this interpretation.
Problem #1: Tongues is not in the context of Paul's letter to the Ephesians.
Problem #2: Not everyone has the gift of tongues (1 Cor 12:30; 13:5). I do not have this gift.
