Matthew Henry on Deuteronomy 26:12-15

How should the earth yield its increase, or, if it does, what comfort can we take in it, unless therewith our God gives us his blessing? All this represented the covenant relation between a reconciled God and every true believer, and the privileges and duties belonging to it. We must be watchful, and show that according to the covenant of grace in Christ Jesus, the Lord is our God, and we are his people, waiting in his appointed way for the performance of his gracious promises.
