This is challenging. It will strike a chord with all of us who pursue security and safety in other things (job, money, relationships, children) and not in God alone. So, how can you get on that balance beam and take a risk for the kingdom of God today?
UPDATE: BTW ... I don't agree with Chan's example of homeschooling being the "safe" option. Sending your children to public school or a Christian school can also be deemed as safe depending on how you look at it. His challenge is good, but making a caricature of homeschooling is unhelpful and ends up dividing the church.
