My son, God will provide himself a lamb — This was the language either, Of his obedience; we must offer the lamb which God has appointed now to be offered; thus giving him this general rule of submission to the divine will to prepare him for the application of it to himself. Or, Of his faith; whether he meant it so or no, this proved to be the meaning of it; a sacrifice was provided instead of Isaac. Thus, Christ the great sacrifice of atonement was of God's providing: when none in heaven or earth could have found a lamb for that burnt — offering, God himself found the ransom. All our sacrifices of acknowledgement are of God's providing too; 'tis he that prepares the heart. The broken and contrite spirit is a sacrifice of God, of his providing.
