give thanks in all circumstances; for this is God’s will for you in Christ Jesus.
Spend time in prayer thanking God for his goodness. Thank him with a grateful heart for all that he is doing in your life. Remember to thank him for what he has done for you in the past. Thank him for what he will do for you in the future. No matter what is going on in your life there is always something to be thankful for.
All the days of the oppressed are wretched, but the cheerful heart has a continual feast.
You can choose to be worried and troubled or you can choose to trust God and be happy. The way to a happy heart begins in giving thanks to God in every situation. You can always find something to be thankful for even if you have to look a little harder. Be grateful for the little things that God can use to fill your heart with joy.
