"He is the LORD our God; his judgments are in all the earth. He remembers his covenant forever, the word he commanded, for a thousand generations, the covenant he made with Abraham, the oath he swore to Isaac." -- Psalm 105:7-9
Have you noticed the limitations of your warranty for that appliance you just purchased? The time limit may be a year or less with restrictions in various states. A lifetime warranty is most often reserved for a few special items and most often limited to the original buyer. Forever commitments are constantly swallowed up by unending limitations.
As the Psalmist walks the reader through the historic working of God, the covenant the Lord made with Abraham stands out without limitations. When God makes a promise, he will keep his word "for a thousand generations". This is the nature of God and can be seen throughout all the pages of Scripture. We can depend on God's commitments because they swallow up unending limitations.
If you will take time to journey through the Old Testament you will come face to face with the God of all faithfulness. Look closely my friend and be encouraged in the Lord's remembering his covenant forever. As you consider this great fact be assured that the Lord will never fail to fulfill his promises to you. His commitments to his children will always swallow up every limitation.
