According to Merriam Webster’s Dictionary, the word unity has several definitions. It can mean, “the quality or state of not being multiple : ONENESS” or “a condition of harmony : ACCORD.” This is what Jesus meant in John 17:21-22 when he prayed and said, “I pray that they will all be one, just as you and I are one-as you are in me, Father, and I am in you. And may they be in us so that the world will believe you sent me. I have given them the glory you gave me, so they may be one as we are one.” His desire was for the body of Christ to be one, unified body and in one accord! What a beautiful picture of how His church should be.
The trinity includes God the Father, Jesus the Son, and the Holy Spirit. They are three in one, unified and in one accord. Everything Jesus did was to serve and please God the Father. He prayed to God. He worshipped God. Everything the Holy Spirit does for us is to serve God the Father. As a body of Christ, we should be the same way. We should live to please God the Father and worship Him. Our decisions should be based on our prayers and seeking after the Lord.
If we are tearing each other apart, slandering someone in the body, or working for ourselves rather than the Lord, then we are not serving God or bringing glory to His name. We should work together in service and in one accord in worship, living and praising in harmony.
