Become complete. Be of good comfort. (2 Corinthians 13:11 NKJV)
Finally, brethren, farewell. Become complete. Be of good comfort, be of one mind, live in peace; and the God of love and peace will be with you. (2 Corinthians 13:11 NKJV)
Make sure that your endurance carries you all the way without failing, so that you may be perfect and complete, lacking nothing. James 1:4
To be complete is to be whole and to get whole is to be holy. This godly reminder is instructing us to become complete. Jesus was complete and Paul was complete. It does not mean that we become perfect the way God is perfect but it means constant desire to please God and being mature in Christ and all the fruits of the Holy Spirit. It means being blameless and keeping our vessels holy as we become vessels of honor. It is possible because the Scripture above is telling us to be complete.
Now may the God of peace who brought up our Lord Jesus from the dead, that great Shepherd of the sheep, through the blood of the everlasting covenant, make you complete in every good work to do His will, working in you what is well pleasing in His sight, through Jesus Christ, to whom be glory forever and ever. Amen. (Hebrews 13:20-21 NKJV)
Only the blood of Jesus can make us clean and complete because it washes away our sins and empowers us with grace to live a godly life. It is not by our own power or might. It is only God that will make us complete through the blood of the everlasting covenant as we desire and pray for all grace from the throne of grace.
And the God of all grace, who called you to his eternal glory in Christ, after you have suffered a little while, will himself restore you and make you strong, firm and steadfast. 1 Peter 5:10
All grace is what leads to completeness. May all grace be upon us in Jesus name.
