1 John 2:1, If anyone does sin, we have an advocate with the Father, Jesus Christ the righteous.
Thus, any other advocate before the Father who is not Jesus Christ the Son of God is inadequate. He alone advocates for us before the Father. No saint who has gone before us, not even Mary herself, can stand before God the Father on our behalf. For what reason or justification do they have to offer that is greater than the sacrifice of the body and blood of the Son of God? This does not devalue intercessory prayers of living saints, since these are exhorted by the Scriptures and Christ stands as our High Priest before God, before whom He offers the sacrifice of our prayers (Hebrews 4:14-16). Therefore, there can be no greater comfort than the knowing that Christ Himself is interceding for our sins before the Father. Thus, “If we confess our sins, [God] is faithful and just to forgive us our sins and to cleanse us from all unrighteousness” (1 John 1:9) based on the merit of Christ alone. Christ holds up our sins before God, which are covered in His blood, and God judges them blameless because Christ has paid the price with His own life.
LORD, we confess our numerous faults,
How great our guilt has been:
Foolish and vain were all our thoughts,
And all our lives were sin.
But, O my soul, forever praise,
Forever love, His name,
Who turns thy feet from dangerous ways
Of folly, sin, and shame.
‘Tis not by works of righteousness
Which our own hands have done,
But we are saved by love and grace
Abounding through His Son.
‘Tis from the mercy of our God
That all our hopes begin;
‘Tis by the Water and the Blood
Our souls are washed from sin.
‘Tis through the purchase of His death
Who hung upon the tree.
The Spirit is sent down to breathe
On such dry bones as we.
Raised from the dead, we live anew;
And justified by grace,
We shall appear in glory too,
And see our Father’s face.
