How great he is, then, and how great His power! It is this God who is on our side, and it is in His world that we live, walk our pilgrim way, and meet the experiences of life. Yet our relationship goes beyond that of creature to Creator. ‘Our help’, says David, ‘is in the name of the Lord’ (verse 8a). Wherever we read of his ‘name’ our minds should at once fly back to Exodus 3:15. His ‘name’ declares who and what He is: He is the Lord who came to Egypt to save us when we were helpless and hopeless, and who, in doing so, revealed Himself to us, His chosen children (Exodus 4:22) and His redeemed (Exodus 6:6). He is our God for ever and ever, our Guide even to death (Psalm 48:14).
