Yesterday, we took a faith test. Today, let’s take an acid test. In 2 Corinthians 13:5, Paul adjures Christ-followers to test themselves to determine if Christ is indeed in them. Paul uses the words, “examine yourselves” for an important reason. Used here, the word “examine” means to carefully scrutinize. To query and question. To observe in all aspects with the purpose of forming a correct judgement. During the gold-rush of the 1800’s, gold miners developed an “acid test” to determine the difference between pure gold and its imposter, fool’s gold. Something that looks real but, once carefully examined, is deemed to be fake. Pouring acid on gold burns away any dross - any waste materials that may have adhered to the gold. The acid test proves authenticity. Today, take God’s acid test. Pour God's presence on your heart. Ask him to burn away any dross - sin and impurities - in your life. Ask him to rid your life of anything that is not of him. Or that which keeps you from him. Jesus said, “Blessed are the pure in heart, for they shall see God” (Matt. 6:5). Is your heart pure? God wants it to be. Take the acid test and ask God to reveal any impurities in your life. He is faithful to do so.
