When you pray in the Spirit you will be praying under the inspiration of the Holy Spirit. This can be achieved by either praying in a language you understand and in line with God’s word or by praying in unknown tongues (may not be understood by you) as inspired by the Holy Spirit or both (1 Cor.14:2). Such prayers are in accord with the will of God (Rom 8:26). Praying in the Holy Spirit therefore touches the heart of God and he releases answers to meet needs. God watches over His word to perform.
