Explain that we sometimes say somebody is blessed when they have lots of good things. The good things might not be stuff like toys and clothes; it could be things like feeling well, and good friendships. Christians believe God blesses them by giving them good things.
The Bible teaches that Christians can bless other people by praying that God will give them good things too. However the Bible also says that people can bless God. But how can they bless Him? Christians believe they bless God by giving Him good things – their time, their attention, their love and their praise; they believe that these are all good things God loves to receive.
In Psalm 34 David said he was going to bless God by giving Him praise. David said that he was going to bless God all the time.
