speak in tongues

The Holy Spirit was coming with all his fruits and gifts. One of his gifts is 'speaking in tongues.' We don't know really how and what to pray as it ought to be. Therefor we got the gift of 'speaking in tongues.'

Be still for God and wait for Him. There are so many, many things to pray for and to thank for. Too many! In that case, with that feeling, I 'll open my mouth in my mind and say the words I don't know what they mean, but they come in a stream and they are prayer to God. Its relaxing connection with God through the Holy Spirit. Very simple and very helpful in your prayers.

'And in the same way-by our faith- the Holy Spirit helps us with our daily problems and in our praying. For we don't even know what we should pray for, nor how to pray as we should; but the Holy Spirit prays for us with such feeling that it cannot be expressed in words. And the Father who knows all hearts knows, of course, what the Spirit is saying as he pleads for us in harmony with God's own will.'

Romans 8:26,27

'So a person "speaking in tongues" helps himself grow spiritually, but one who prophesies, preaching messages from God, helps the entire church grow in holiness and happiness.'

1 Corinthians 14:4

So you see friends "speaking in tongues" helps you to grow spiritually but is not the biggest gift. That gift is LOVE!!
Please read 1 Corinthian 13 and 14. All about the gifts of the Holy Spirit.The fruits of the Holy Spirit you 'll find in Galatians 5 :22,23.
