1 Corinthians 6:20

bought with a price--Therefore Christ's blood is strictly a ransom paid to God's justice by the love of God in Christ for our redemption (Mat 20:28; Act 20:28; Gal 3:13; Heb 9:12; Pe1 1:18-19; Pe2 2:1; Rev 5:9). While He thus took off our obligation to punishment, He laid upon us a new obligation to obedience (Co1 7:22-23). If we accept Him as our Prophet to reveal God to us, and our Priest to atone for us, we must also accept Him as our King to rule over us as wholly His, presenting every token of our fealty (Isa 26:13). in your body--as "in" a temple (compare Joh 13:32; Rom 12:1; Phi 1:20). and in your spirit, which are God's--not in the oldest manuscripts and versions, and not needed for the sense, as the context refers mainly to the "body" (Co1 6:16, Co1 6:18-19). The "spirit" is incidentally mentioned in Co1 6:17, which perhaps gave rise to the interpolation, at first written in the Margin, afterwards inserted in the text. Next: 1 Corinthians Chapter 7
