“He calls to the heavens from above and to the earth to contend with his people.”
The structure of this passage is much like that of a court case. And though God is always true and none can contend against him, as he is just, he follows his own rules and guidelines. Indeed, for a capital sentence to be given, two or three witnesses must be presented (Deuteronomy 19:15; Matthew 18:16). And so, God furnishes witnesses as such. Here he calls to the heavens and to the earth — that which suffered in the place of Adam in Eden (Genesis 3:17), that which testifies to the glory of God (Psalm 19:1), that which still yearns for its own redemption (Romans 8:22) — and he demands that they take a stand to witness not only the faithlessness of the people of God to the covenant but also of God’s faithfulness to the covenant as well.
The remarkable thing about this is not so much that God is calling his people to task, they deserve it, but it is that he is calling his people to task again and again. How remarkably patient our God is with we who are his people! How gracious he is in every way. How merciful. God’s aim for us is a life of repentance and faithfulness; how rarely we live in such a way. Perhaps this is one more reminder indeed, to repent and walk faithfully before him lest the heavens and earth testify against us as well.
