Good morning! There are four types of prayers in this verse and a direction on who and why to use them. Supplications are like petitions and even a begging of God for Him to move over a situation or person. Prayers are just that, prayers.
Intercessions are standing in the gap especially for someone to be saved much like Moses did for the Israelites. Finally, being thankful is giving God thanks and praise even when you have a hard time with being thankful. It's important to have an attitude of gratitude.
It's not always easy to do this for all people, leaders and authority figures, but it's not about them being honorable, but us honoring the offices they hold. When we pray for them to become Godly people, it helps to lead our nation to a place of peace and morality.
Prayer is important in causing the nation to be at peace, people to be saved and morality to abound. Pray today in this manner to make a great day!
