This sermon [podcast] by Francis Chan is based on Philippians 3 & 4. "But I press on to reach the end of the race and receive the heavenly prize for which God, through Christ Jesus, is calling us....There are many whose conduct shows they are really enemies of the cross of Christ. Their god is their appetite, they brag about shameful things, and they think only about this life here on earth. But we are citizens of heaven, where the Lord Jesus Christ lives. And we are eagerly waiting for him to return as our Savior." (Philippians 3:14,18b-20 NLT)

There's very little I can add to the message of this sermon. It wraps up all of the thoughts I could really say on the matter. But recently, I've been contemplating two verses, one where Paul talks about running the race to win the prize and disciplining his body like an athlete. The other is "never grow weary of doing good" (2 Thessalonians 3:13). Both are about constantly working and striving to bring others to Christ, to discipline ourselves like athletes to be able to preach the gospel well and save the lost. I've had several moments of indecisiveness about situations where I could be selfish and do what I want, or do what would be best for someone else. "Never tire of doing good" goes through my mind, and my decision is made.
