“Likewise the Spirit also helps in our weaknesses. For we do not know what we should pray for as we ought, but the Spirit Himself makes intercession for us with groanings which cannot be uttered. Now He who searches the hearts knows what the mind of the Spirit is, because He makes intercession for the saints according to the will of God. And we know that all things work together for good to those who love God, to those who are the called according to His purpose.” Romans 8:26-28 (NKJV)
Holy Spirit prays for us with groanings: 1 Thessalonians 5:16-22(NKJV)
Holy Spirit of God is the one who helps us to pray: otherwise we do not know how to pray for any need or for any person. So our earnest prayer first should be to receive the anointing of the Holy Spirit to be on the right path in prayer life and spiritual life. God was on earth in flesh as Jesus and God is the one who is Spirit now, who can live in us and work through us. For this all the believers got to allow God to do that by keeping aside our own agendas and allow God to take over us and do His agendas.
Holy Spirit prays according to the Will of God: 1 Corinthians 14:1-2(NKJV)
When God lives and does things through us, then all things work together for us: because He Himself will pray with groanings and intercede for our requirements and the devil will not understand what is happening so he cannot hinder us also. If we do not desire the Holy Spirit or allow His power work in us then we are without help and in trouble. Holy Spirit prays the right prayers to receive the right answers because He knows the will of God.
Receive Holy Spirit power: 2 Timothy 1:7-9(NKJV)
Just like we need physical power to operate in the physical realm, we need spiritual power to operate spiritually. Jesus said we have to receive this power from above which is the anointing of the Holy Spirit to operate. It is not an option to receive the Holy Spirit, as some try to project, rather compulsory requirement to receive the Holy Spirit power to live a spiritual life, which is life abundant. There is a spirit of fear operating in the world, which should be overcome by the Spirit of power, love and sound mind from heaven; which is God Himself coming to live in us.
“But as it is written: “Eye has not seen, nor ear heard, Nor have entered into the heart of man The things which God has prepared for those who love Him.” But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God. Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God.” 1 Corinthians 2:9-12 (NKJV)
