"This I say, therefore, and testify in the Lord, THAT you should no longer walk as the rest of the world..." (Ephesians 4:17)
"...our Lord Jesus Christ, who gave Himself for our sins, that He might deliver (pluck us out/rescue) us from this present evil age..." (Galatians 1:4)
There is an eternal effectiveness of the gospel of grace.
Those redeemed by Jesus have been plucked and planted β plucked from the realm of darkness and placed and planted in the kingdom of light and love.
As Paul teaches (Colossians 1:12-14) and when he said: "When Christ who is your life appears..." (Colossians 3:4)
It's not that we give Him the MOST or BEST of ourselves or Him being the BEST part of our lives... the priority is that He is our life and that He has ALL of us. HE gave us His life so we can give Him our lives, again and again, that He may present Himself within us and prove through our lives the wonders and wisdom of His grace.
