1. The Holy Spirit makes intercession for the saints according to the will of God.(Rom 8:26-27)
    Jn 6:29, Jn 6:39, Acts 1:8, Act 4:31, Jn 16:13, Jn 14:26

We do not know what to pray for. So the Holy Spirit sighs and prays for us according to the will of God. (Rom 8:26-27)

Rom 8:26 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
27 And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.

The will of God is to believe in Jesus, the one whom God has sent, as the Christ. (Jn 6:29)

Jn 6:29 Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.

Also, God’s will is to find all of God’s children. That is, world evangelization. (Jn 6:39)

Jn 6:39 And this is the Father’s will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.

The Holy Spirit enables us to know more and more that Jesus is the Christ, and to spread the gospel and evangelize the world. (Jn 16:13, Jn 14:26, Acts 4:31, Acts 1:8)

Jn 16:13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.

Jn 14:26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.

Acts 4:31 And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness.

Acts 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
