“Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ” Ephesians 5:20.
Some people complain about everything, despite the fact that there are a lot of good things happening in their lives. This is their attitude that really has to be blamed. They focus on the bad stuff and fail to see the good that God gives them. On the other hand, if you search for things that you can praise the Lord for, you will find countless instances where the Lord showed you His goodness. Look for the good and it will increase, forget the bad and it will decrease.
