At the Lord's Supper, believers are invited to eat and drink as we remember and give thanks for Jesus, who has set us free. But what does it mean to be free in Christ? Alistair Begg examines two short verses in Galatians 4 that summarize Christ's work and remind us of the immense privilege of knowing God. We are free because Christ has fulfilled the law as our representative and assumed the penalty for our sin on the cross. As adopted sons and daughters, our freedom, confidence, and security are in Him alone.
