God the Father is the Source of all things and Jesus is the Channel.
Eph 4:6 One God and Father of all, who is above all, and through all, and in you all.
The Spirit flows from God, through the Son, to us.
The Holy Spirit proceeds “from the Father”
Joh 15:26 But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me:
From the Father to His Son
Tit 3:6 Which he shed on us abundantly through Jesus Christ our Saviour;
Joh 3:34 For he whom God hath sent speaketh the words of God: for God giveth not the Spirit by measure unto him.
Gal 4:6 And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.
Then we can have personal fellowship with both the Father and His Son.
1Jn 1:3 That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.
“He that acknowledgeth the Son hath the Father also.”
1Jn 2:23 Whosoever denieth the Son, the same hath not the Father: (but) he that acknowledgeth the Son hath the Father also.
We have the Spirit of God/Christ (they both shared the same Spirit) abide in our hearts.
Eph_2:18 For through him we both have access by one Spirit unto the Father.
Joh 14:23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.
Christ in you the Hope of Glory
Eph 3:17 Christ dwells in your hearts
Rom 8:10 If Christ is in you, the body is dead…but the Spirit is life
2Cor 5:17 if anyone is in Christ he is a new creation
Gal 4:19 Christ is formed in you
Col 1:27 God's mystery among the Gentiles: Christ in you the hope of glory
