People do not know what to pray and how to pray but Jesus sent us the Holy Spirit to help us. The Holy Spirit convicts the world of sin, righteousness and judgment and draws us unto Jesus. The Holy Spirit is the Spirit of Christ who wants to help us to become children of God and be pleasing to God.
When we pray and seek earnestly to be pleasing to God then the Holy Spirit puts the words in our mind because the Holy Spirit knows what we need and the Holy Spirit intercedes for us according to the will of God but we ourselves have to DRAW CLOSER TO GOD. We have to SEEK JESUS, we have to turn from wickedness and OBEY the Spirit of God who is pleading with us and HE WILL HELP US. He will assist us, He will teach us to pray, He will guide us but we have to yearn and seek for Jesus. We have to seek God and He will help us.
If we OBEY Jesus and we REPENT, we turn from wickedness and we live in holiness and righteousness and are baptized in water, then He gives His Holy Spirit to live in us, to be WITH US, to guide us in everything. The world cannot receive the Holy Spirit because it does not receive Jesus Christ.
Seek Jesus and the Holy Spirit will ASSIST you to pray, with guide you, will teach you and will reveal Jesus Christ to you. The Holy Spirit will help you IF you seek Jesus.
May Jesus bless you.
