So to me grace means salvation through his son Jesus, certainly not any good works I could do, Mercy means He doesn't get out that big eraser and take my name out of the book of life when I sin and separate myself from Him that's what sin does it's a separator !!!! Fearing God is good !!!
It helps fill up your grace and mercy buckets :-)
Grace, Grace, God's Grace,Grace that is greater than all my sins!!!! That's a great song ,enjoy your Thursday.
