So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal.
Paul in his first letter to the Corinthians in our Bibles tells us that if Christ was not raised from the dead, then there’s no resurrection of the dead for us who believe in Christ, and our faith is then worthless (1 Corinthians 15:12-19). In the context (click link above), Paul is talking about fixing our eyes on what lies beyond the weakness of this present life. He makes it clear that in their following of Christ, the calling they had, their lives were on the line. This was especially true of Paul himself, who was the target of relentless attacks from those who opposed the gospel, those determined to see his life come to an end.
Today it is no less dangerous to be a Christian in some places, in fact one’s life or well being is in some way in jeopardy in many places (see Open Doors for information on this). And as I get older, I realize more and more that my days in this present life are less and less, that they are indeed numbered.
Paul encourages us to press on, fixing our eyes on what is to come in the resurrection, so that we are willing to risk it all for Christ in the present, and also so that we don’t see holding on to life as the end all, because it’s not for those of us who are “in Christ.”
Paul is not advocating a “grin and bare it” approach. Instead we’re to rejoice in the midst of our weaknesses and sufferings, because Christ and his life is present with us now, someday to be completed in no less than our resurrection when we receive our new body, raised with other believers to be presented to Christ to the glory of God.
In the mean time we live in bodily weakness, even for those of us who have a measure of good health. We enjoy God’s good creation, but we live as those who look to the new creation in Christ as present in this life for ourselves and others, and the promise in that when this life ends. In and through Jesus.
