So we are always of good courage. We know that while we are at home in the body we are away from the Lord, for we walk by faith, not by sight.
2 Corinthians 5:6-7 (ESV)
In this chapter, Paul gives us a living example of what our true aspiration and goal should be. While still living in his body, he anticipated what awaited him in heaven. His love for God and his attachment to the word made him feel that he was far from his Lord with whom he desired to be; he looked forward to his glorified body in the presence of God.
As Christians, we too should develop such an attitude, have such an aspiration with heaven in view. Not because we don't want to be with our loved ones who live with us on this earth, but rather because our love for God and our desire to be in His presence must go beyond our attachment to earthly things. As Paul so aptly put it, the only reason he still lived in his body was to serve the Lord.
Having heaven in perspective should be the central goal of every believer. I am not saying that we should give up our life in this body, far from my intention, but by faith we must look to Jesus who has already prepared a safe place for us in heaven. Meanwhile, in this body, our responsibility is to share the gospel in order to bring more hearts to repentance.
