It is all about selfless love that we have for the body of church in the present world. There are two essential aspects of life registered for teaching of the gospel of the truth. And both of them are juxtaposed in the above verse. One area of our godly and church led community life tells about what I possess and have and the other describes about how I become nothing in the church community life when I live and do something without love.
St. Paul states that he is nothing without selfless love for the church. Strong biblical expositions, wisdom and knowledge to unravel the gospel of Christ, sense of endurance and perseverance to overcome the suffering for the sake of Christ and His gospel without godly love for the church and its community are insignificant.
It is neither our genius redirected to join with the Lord Jesus to participate in His kingdom business nor our ardent and unshakable faith in Him amidst our personal losses matter to God. It is our godly love without selfish desires which keep the church in front of the self and runs the race of the eternal marathon that pleases our Lord Jesus.
Everything including preaching and teaching of the gospel, sharing biblical knowledge and wisdom with others, unraveling the truth of Christ, and enduring the sufferings for the glory of God is done in pure love with in the church community. We do not engage with the above greater tasks in an island. They all take place and the outcomes are witnessed in Bible believing church communities.
