S – They exchanged the truth of God for a lie, and worshiped and served what has been created instead of the Creator, who is praised forever. Amen. 

Romans 1:25 CSB

O – Commentary:

The truth of God is not only the truth concerning God but also God’s truth concerning all things, including mankind. This truth is that people are creatures of God and can find true fulfillment only in worshiping and obediently serving God the Creator. A lie (lit., “the lie”) on the other hand says that the creature—angelic (Isa. 14:13–14; John 8:44) or human (Gen. 3:4–5)—can exist independent of God, self-sufficient, self-directing, and self-fulfilling. Mankind made himself his god in place of the true God. Because God the Creator is forever praised (in contrast with creatures who are undeserving of worship), Paul added Amen. This word transliterates in both Greek and English the Hebrew word meaning “so let it be.” As an affirmation, not a wish, it places approval on what has just been said 

“Romans,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

A – We must worship God in spirit and in truth.  To do this, we need to know the truth.  Knowing God and His Word gives us the foundation of who God is, His heart and character and his power.  When someone knows this and believes they can live separate from God, they are living a lie.  

R – Heavenly Father, you are the one and only God.  Continue to reveal your truth to us daily.   Let us grow in our understanding of this so we are not distracted by any lies or false entities.  We desire to walk in relationship knowing you fully and being fully known.
