Not only is 1 Corinthians 15 a very important chapter of the Bible because of what it teaches about the resurrection, but also for what it teaches about reality and how we should perceive it. In answering the claim of some in the church of Corinth that there is no resurrection Paul says in verse 12:
“Now if Christ is proclaimed as raised from the dead, how can some of you say that there is no resurrection of the dead?”
He then goes on to defend this all-important doctrine. But one thing that we should also learn from this verse (indeed from the whole chapter) is that we must not limit reality to our own understanding or personal experience (as important s these can be), but we must understand reality by what God has done through Jesus Christ and by what is proclaimed in his word.
This is not a call to abandon reason. If you read 1 Corinthians 15 you can see it is carefully reasoned! Instead, this is a call to abandon the weakness and limitations that come with seeing things only through the eyes of unbelief. To see things this way we need faith, and this faith will help us to better reason on the basis of what is actually real, instead of being wise in our own eyes. Even the ability to look at reality in this way comes from God who gives us his Spirit, and the Spirit helps us to understand as see reality through the word of God (1 Cor 2:6-16).
Thank you, Lord, for helping us to see.
