This prayer teaches us that we can hear God’s desire for every situation in our life and live life in the moment . In the Serenity Prayer we ask God to give us the wisdom to know what situations we can change, and which to leave in His hands. If you cannot change them, then praise God for them, in them, and through them - even for the negative things. By doing this, you end up walking in complete serenity and in the dynamic power of the Spirit of God.
If you can do something about it, do it. If you can't, then give it to God...No! I mean, really give it to God. Then you can deal with the emotions or circumstances or put them in God’s hands before you go on to the next moment ~ experiencing each moment fully and deliberately with thought, prayer and purpose. You end up going about your day in the peace of God that passes all understanding.
Ask God for the strength to deal with the issues that He reveals are your responsibility. Then turn the rest over to the Lord and ask God to help you to develop an attitude of acceptance about them. What is it in your life that is causing you a problem right now? Can you do something about it? Then, do it! If not, then change your focus and give the problem to God. Would you like to have your life changed? The Holy Spirit is present to fill you with all the fullness of God, and to help you to walk one moment at a time. This is the key to walking in Serenity.
