Does God want us to have a spirit of contemptment or a spirit of joy? Are the two mutually exclusive?
I think you mean “contentment”, not “contemptment” as those words are very different. Being content and being joyful are not mutually exclusive. In fact I think that being content and being joyful go together. It’s hard to be content without having a sense of joy. Likewise, it’s hard to be joyful without having some sense of contentment. So to answer your question, God wants us to have both joy and contentment as the two go hand in hand.
My questions are not about the sermon, but more in the application, maybe? Many of my prayers of supplication lately are for God to act on behalf of refugees or immigrants suddenly left stranded upon the President's executive order a couple days ago. How do we pray for our leaders in this situation? How do we pray for refugees and immigrants in this time?
God calls us to pray for “all those in authority” (I Timothy 2:1-2). Then, in the next verse, we learn that praying for those in authority “pleases God our Savior, who wants all men to be saved and to come to a knowledge of the truth” (I Timothy 2:3-4). In other words, God’s first priority is for the salvation of all people – government officials, immigrants, refugees, everyone. So we should pray that God would use a complicated and messy political situation to the end that many would come to know Jesus as Savior and Lord. Of course, we continue to pray that our national leaders would be just and wise, but we remember that God’s priority is to rescue lost people.
