Run, don't walk, and listen to this sermon by John Piper: Adoption, the Heart of the Gospel.
'When people embrace the pain and joy of children rather than using abortion or birth control simply to keep children away, the worth of Christ shines more visibly. Adoption is as far as possible from the mindset that rejects children as an intrusion. Praise God for people ready to embrace the suffering—known and unknown. God’s cost to adopt us was infinitely greater than any cost we will endure in adopting and raising children.'
