Grace from God toward us – unmerited favor, getting favor we do not deserve
Eph 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God
Grace from us toward God – To dignify or raise by act of favor; to honor
Col 3:16 Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
