Romans 2
17 [d]Indeed you are called a Jew, and rest[e] on the law, and make your boast in God, 18 and know His will, and approve the things that are excellent, being instructed out of the law, 19 and are confident that you yourself are a guide to the blind, a light to those who are in darkness, 20 an instructor of the foolish, a teacher of babes, having the form of knowledge and truth in the law. 21 You, therefore, who teach another, do you not teach yourself? You who preach that a man should not steal, do you steal? 22 You who say, “Do not commit adultery,” do you commit adultery? You who abhor idols, do you rob temples? 23 You who make your boast in the law, do you dishonor God through breaking the law? 24 For “the name of God is blasphemed among the Gentiles because of you,” as it is written.

This.

 

God applies His law to both our actions and our attitudes. Sometimes we only want our attitudes evaluated, and sometimes only our actions. God will hold us accountable for both motives and actions.

AND this.

Paul reminds the Jew that God said in the Old Testament that the failure of the Jew to obey the law causes Gentiles to blaspheme God.

When we act terrible and blend in with the world, God is the one who suffers. The gentile will either curse God because He(God) fails the Christian and the gentile wants no part of this, or the gentile will think God is a fraud because “these Christians” are no different than the world.

This is why we must rise above. This is why we must believe for bigger things. We are a testimony to the lost. Are lives should be a light.
