Below is a current study of how the words Faith and Grace are used in the Pauline Epistles Galatians, Ephesians, Philippians, Colossians, 1 and 2 Thessalonians.

Of particular note is the relationship between Faith and the Lord Jesus Christ and then in turn with Grace.

The Cross represents the dramatic, faithful conclusion of Christ’s ministry in the flesh, having entered the world of Space-Time as the very Word of God.  An deeper examination of this aspect of Christ’s faithfulness is given here.

A touching hymn expressing our faith in Christ’s Redeeming Faith, and the character of Christ’s Faith is “My Redeemer is Faithful and True.”  The lyrics to this hymn are given below.  A particularly beautiful singing of this hymn is by Bobby Michaels, late founder of Musicianaries.  A youtube source of Bobby Michaels singing this hymn is here.  According to his bio, the “My Redeemer” hymn was his favorite recording.  And his life verse was:

Zephaniah 3:17 English Standard Version (ESV)

My Redeemer is Faithful and True

[Written by James Isaac Elliott and Steven Curtis Chapman, based on Psalm 103:17]
As I look back on the road I’ve travelled,
I see so many times He carried me through;
And if there’s one thing that I’ve learned in my life,
My Redeemer is faithful and true.
My Redeemer is faithful and true.
[Chorus:]
My Redeemer is faithful and true.
Everything He has said He will do,
And every morning His mercies are new.
My Redeemer is faithful and true.
My heart rejoices when I read the promise
‘There is a place I am preparing for you.’
I know someday I’ll see my Lord face to face,
‘Cause my Redeemer is faithful and true.
My Redeemer is faithful and true.
[Chorus]
And in every situation He has proved His love to me;
When I lack the understanding, He gives more grace to me.
[Chorus]

There’s a stunning background story on how Bobby found this song to record.  It is told in a book by Bill Cowder, The Spotlight of Faith: Understanding What It Means to Walk with God:
