In Psalm 9:17 David writes: “The wicked will return to Sheol, even all the nations who forget God.” “The wicked” are in parallel here with “all the nations who FORGET GOD.” This should remind us that it is wickedness to forget God — which is exactly what even many of God’s people do constantly: we forget God.

— We get up in the morning and walk right out into the day without praying or reading His word — we forget God!
— Or if indeed we DO have a devotional time in the morning, we then leave it behind as if it never happened and go into the day forgetting God.
— We face our enemies in fear and forget God
— We are engulfed in circumstances and forget Him
— We are confronted with temptation and forget Him
— We are immersed in entertainment and we forget Him
— We go through the bulk of our day forgetting Him

It should be a cause for self-evaluation for each of us: how often am I no different from the way that God describes “the wicked” in Psalm 9:17? How often in my life do I go through long stretches of time where I just “forget God”?
