“..By {In} His Life.”-{Romans 5:10}.

This speaks of our intimate relationship between the LORD and the believer. The Christian has two address’s, a physical location and a spiritual location, “In Christ.” And in Him we find… and can say based on the authority of His Word…

Christ is now my Sufficiency -{2 Cor 12:9};
Christ is now my Savior -{ Matt 1:21}
Christ in now my Hope- {1 Tim 1:1}.
Christ is now my Sin Bearer- {2 Cor 5:21; 1 John 2:2 }.
Christ is my Advocate with God.-{1 John 2:1}.
Christ is now my Security.- “For you have died and your life is hidden with Christ in God.”-{Col 3:3}

“But by His {God’s} doing you are in Christ Jesus, who became to us wisdom from God,and righteousness and sanctification, and redemption,  so that, just as it is written, “Let him who BOASTS, BOAST in the Lord.”-{1 Cor 1:30-31}.
