So Paul claims that our future glory with God is worth our present sufferings for Jesus. Whatever it will cost you to take the next step with God will repay its cost and more. That's not all the Bible says on the subject.

Rewards in heaven are clearly taught in the word of God.

We receive the "crown of life" when we suffer for faithfulness: "Blessed is the man who perseveres under trial, because when he has stood the test, he will receive the crown of life that God has promised to those who love him" (James 1.12). Jesus said, "Be faithful, even to the point of death, and I will give you the crown of life" (Revelation 2.10).

We receive the "soul-winners crown" for bringing people to Jesus: "What is our hope, our joy, or the crown in which we will glory in the presence of our Lord Jesus when he comes? Is it not you? Indeed, you are our glory and joy" (1 Thessalonians 2.19-20).

We receive the "crown of righteousness" when we remain faithful to our Lord: "I have fought the good fight, I have finished the race, I have kept the faith. Now there is in store for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day—and not only to me, but also to all who have longed for his appearing" (2 Timothy 4.7-8).

We receive the "crown of glory" when we lead with integrity: "Be shepherds of God's flock that is under your care, serving as overseers--not because you must, but because you are willing, as God wants you to be; not greedy for money, but eager to serve; not lording it over those entrusted to you, but being examples to the flock. And when the Chief Shepherd appears, you will receive the crown of glory that will never fade away" (1 Peter 5.2-4).

Rewards can also be lost in heaven.

Secret, unconfessed sins will be judged: "God will bring every deed into judgment, including every hidden thing, whether it is good or evil" (Ecclesiastes 12.14). Jesus confirms this: "There is nothing concealed that will not be disclosed, or hidden that will not be made known" (Luke 12.2).

Our words will be judged: "What you have said in the dark will be heard in the daylight, and what you have whispered in the ear in the inner rooms will be proclaimed from the roofs" (Luke 12.3); "I tell you that men will have to give account on the day of judgment for every careless word they have spoken" (Matthew 12.36-37).

Our sinful actions will be judged: "Let the time that is past suffice for doing what the Gentiles like to do, living in licentiousness, passions, drunkenness, revels, carousing, and lawless idolatry…they will give account to him who is ready to judge the living and the dead" (1 Peter 4.3, 5).

So if we live for heaven, we are rewarded forever. But the paradoxical fact is that living for heaven someday is also the best way to live on earth today.

If I forgive someone I would pardon if Jesus were coming back today, then our Lord waits another 50 years to return, I have still healed a relationship which was broken. If I resist a sin I know I'd refuse if Jesus were returning today, I've avoided spiritual cancer. If I spend time in prayer and Bible study which I know I'd invest to get ready for Jesus' return on Tuesday, I've spent my time wisely.

Living for heaven is the best way to live on earth.
