Grace - mercy, honor, favor.
"Mercy" is forgiveness. Christ taught us from the Alter of the Cross, "Forgive them for they know not what they do".
-We love one another.
"Honor" is presence of the Holy Spirit. Jesus said. "... when the Comforter is come, whom I will send unto you from the Father...
-We turn to God Almighty and we in turn are honored with the presence of the Holy Spirit in us and through us.
"Favor" - is the Gift of Life. God is Life. We are no longer dead spiritually. Jesus said, "fools and blind: for whether [is] greater, the gift, or the altar that sanctifieth the gift?
-Thorough Christ Jesus we learn to have life and have it more abundantly.
God's grace is shown in the salvation of sinners. Christian soteriology deals with salvation as the effect of recognition and repentance.
Deserving and undeserving are man made concepts and impositions on the gift of the Grace of God. The Pharisaical leadership of certain groups pronounce judgment. Jesus states, "Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity".
