5. You will waste your cancer if you think that “beating” cancer means staying alive rather than cherishing Christ.

Satan’s and God’s designs in your cancer are not the same. Satan designs to destroy your love for Christ. God designs to deepen your love for Christ. Cancer does not win if you die. It wins if you fail to cherish Christ. God’s design is to wean you off the breast of the world and feast you on the sufficiency of Christ. It is meant to help you say and feel, “I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord.” And to know that therefore, “To live is Christ, and to die is gain” (Philippians 3:8; 1:21).

6. You will waste your cancer if you spend too much time reading about cancer and not enough time reading about God.

It is not wrong to know about cancer. Ignorance is not a virtue. But the lure to know more and more and the lack of zeal to know God more and more is symptomatic of unbelief. Cancer is meant to waken us to the reality of God. It is meant to put feeling and force behind the command, “Let us know; let us press on to know the LORD” (Hosea 6:3). It is meant to waken us to the truth of Daniel 11:32, “The people who know their God shall stand firm and take action.” It is meant to make unshakable, indestructible oak trees out of us: “His delight is in the law of the LORD, and on his law he meditates day and night. He is like a tree planted by streams of water that yields its fruit in its season, and its leaf does not wither. In all that he does, he prospers” (Psalm 1:2). What a waste of cancer if we read day and night about cancer and not about God.

7. You will waste your cancer if you let it drive you into solitude instead of deepen your relationships with manifest affection.

When Epaphroditus brought the gifts to Paul sent by the Philippian church he became ill and almost died. Paul tells the Philippians, “He has been longing for you all and has been distressed because you heard that he was ill” (Philippians 2:26-27). What an amazing response! It does not say they were distressed that he was ill, but that he was distressed because they heard he was ill. That is the kind of heart God is aiming to create with cancer: a deeply affectionate, caring heart for people. Don’t waste your cancer by retreating into yourself.

8. You will waste your cancer if you grieve as those who have no hope.

Paul used this phrase in relation to those whose loved ones had died: “We do not want you to be uninformed, brothers, about those who are asleep, that you may not grieve as others do who have no hope” (1 Thessalonians 4:13). There is a grief at death. Even for the believer who dies, there is temporary loss—loss of body, and loss of loved ones here, and loss of earthly ministry. But the grief is different—it is permeated with hope. “We would rather be away from the body and at home with the Lord” (2 Corinthians 5:8). Don’t waste your cancer grieving as those who don’t have this hope.
