We must all have the Holy Spirit as our living testimony.
Scripture alone I’m afraid is meaningless..
Premise - Paul quoting OT Scripture not mentioning the Holy Spirit.
Rom 3:10 As it is written, There is none righteous, no, not one:
Rom 3:11 There is none that understandeth, there is none that seeketh after God.
Rom 3:12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
Rom 3:13 Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:
Rom 3:14 Whose mouth is full of cursing and bitterness:
Rom 3:15 Their feet are swift to shed blood:
Rom 3:16 Destruction and misery are in their ways:
Rom 3:17 And the way of peace have they not known:
Rom 3:18 There is no fear of God before their eyes.
Fallacy - Paul does not have the Holy Spirit.
