The Apostles in their writings reveal the Father, Son and Holy Spirit working together in the believers life. They are distinct Persons within the One God.
John 15:26-27
26 "When the Helper comes, whom I will send to you from the Father, that is the Spirit of truth who proceeds from the Father, He will testify about Me, 27and you will testify also, because you have been with Me from the beginning.
John 16:5-8
"But now I am going to Him who sent Me; and none of you asks Me, Where are You going?' 6"But because I have said these things to you, sorrow has filled your heart. 7"But I tell you the truth, it is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I go,I will send Him to you. 8"And He, when He comes, will convictthe world concerning sin and righteousness and judgment;
John 16:13-15
13 "But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. 14"He will glorify Me, for He will take of Mine and will disclose it to you. 15"All things that the Fatherhas are Mine; therefore I said that He takes of Mine and will disclose it to you.
Matthew 3:16-17
16 And when Jesus was baptized, immediately he went up from the water, and behold, the heavens were opened to him, and he saw the Spirit of God descending like a dove and coming to rest on him; 17 and behold, a voice from heaven said, "This is mybeloved Son, with whom I am well pleased."
Below we see the One Name singular and the Plurality of Persons that one is to be baptized in as a disciple .
Matt 28:19-20
19 "Go therefore and make disciples of all the nations, baptizing them in the name of the Fatherand the Son and the Holy Spirit, 20 teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age. "
Now below Paul will lay out our triune God below in these passages.
Rom 8:9-11
9 However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. But if anyone does not have the Spirit of Christ, he does not belong to Him. 10 If Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness. 11 But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you.
Rom 8:14-17
14 For all who are being led by the Spirit of God, these are sons of God. 15 For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, "Abba! Father!" 16 The Spirit Himself testifies with our spirit that we are children of God, 17 and if children, heirs also, heirs of God and fellowheirs with Christ, if indeed we suffer with Him so that we may also be glorified with Him.
Rom 8:26-36
26 In the same way the Spirit also helps our weakness; for we do not know how to pray as we should, but the Spirit Himself intercedes for us with groanings too deep for words; 27 and He who searches the hearts knows what the mind of the Spirit is, because He intercedes for the saints according to the will of God.
28 And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose. 29 For those whom He foreknew, He also predestined to become conformed to the image of His Son, so that He would be the firstborn among many brethren; 30 and these whom He predestined, He also called; and these whom He called, He also justified; and these whom He justified, He also glorified.
31 What then shall we say to these things? If God is for us, who is against us? 32 He who did not spare His own Son, but delivered Him over for us all, how will He not also with Him freely give us all things? 33 Who will bring a charge against God's elect? God is the one who justifies; 34 who is the one who condemns? Christ Jesus is He who died, yes, rather who was raised, who is at the right hand of God, who also intercedes for us. 35 Who will separate us from the love of Christ? Will tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?
Rom 14:17-18
17 for the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit. 18 For he who in this way serves Christ is acceptable to God and approved by men.
1 Cor 2:10-16
10 For to us God revealed them through the Spirit; for the Spirit searches all things, even the depths of God. 11 For who among men knows the thoughts of a man except the spirit of the man which is in him? Even so the thoughts of God no one knows except the Spirit of God. 12 Now we have received, not the spirit of the world, but the Spirit who is from God, so that we may know the things freely given to us by God, 13 which things we also speak, not in words taught by human wisdom, but in those taught by the Spirit, combining spiritual thoughts with spiritual words.
14 But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised. 15 But he who is spiritual appraises all things, yet he himself is appraised by no one. 16 For WHO HAS KNOWN THE MIND OF THE LORD, THAT HE WILL INSTRUCT HIM? But we have the mind of Christ.
1 Cor 12:3-6
3 Therefore I make known to you that no one speaking by the Spirit of God says, "Jesus is accursed"; and no one can say, "Jesus is Lord," except by the Holy Spirit.
4 Now there are varieties of gifts, but the same Spirit. 5 And there are varieties of ministries, and the same Lord. 6 There are varieties of effects, but the same God who works all things in all persons.
Titus 3:4-7
4 But when the kindness of God our Savior and His love for mankind appeared, 5 He saved us, not on the basis of deeds which we have done in righteousness, but according to His mercy, by the washing of regeneration and renewing by the Holy Spirit, 6 whom He poured out upon us richly through Jesus Christ our Savior, 7 that being justified by His grace we might be made heirs according to the hope of eternal life.
hope this helps !!!
