“You are not your own; you were bought at a price”. 

1 Cor 6:19, 20 NIV 

There is a saying that goes, “Every man has his price”. It is a cynical comment that reflects how some people will allow themselves to be co-opted into some unethical conduct if the reward is high enough. 
When Paul addressed his friends in Corinth he was not referring to that kind of situation. The cross of Jesus and his resurrection were never very far from Paul’s mind. Most problems in the churches could be met by applying some interpretation of the cross. Paul regarded himself as a slave of Christ. Slaves were traded in the slave market like goods and chattels. But a slave could be released from his slavery if he could raise sufficient money or if someone was prepared to buy him out. This was called paying the ransom. For Paul, so great was Christ’s love for Christian believers that his death on Calvary paid their ransom to set them free from slavery to sin. But it also meant they were now God’s people and slaves of Christ. They were not free to do anything, good or bad. They were only free to obey Christ and serve him willingly. Therefore they had to conduct themselves in accordance with the will and purpose of Christ and that involved a disciplined and dignified management of their bodies, such as would glorify God and honour Jesus Christ. 
It is good for Christian believers to know and understand this concept of Paul. You are not your own. You belong to God in Christ Jesus as a result of the price Jesus paid by his death on Calvary. Conduct yourself out of love and gratitude to Christ. 

Lord, let me bring my every action into line with your will.
