If we rejoice in who our Lord is then we need not worry. Knowing our God we are free to bring our requests to our Father with thankful hearts. Unfortunately we live in a day when we are trained to be dissatisfied. A principle of advertising is to make the consumer unhappy with his or her lot in life so that he or she will go out and purchase something to make him or her happier. Opposition politicians seek to make the electorate dissatisfied regardless of what transpires in the hope of creating enough dissatisfaction to have them voted into power.
Courts tend to be adversarial and the media reports tragedy, strife and discord.
Wherever we turn we are encouraged to be discouraged. This seems to be a paradoxical part of living in our day. And as Christians it can be difficult to have a thankful disposition in this sometimes poisonous environment. And there are those times when we simply cannot rejoice and bless the Lord. It is beyond us.
