The section Paul's letter to the Galatians we are reading now can come across as a Conde,nation of the Jewish faith. What Paul is really saying to the people is that they must decide. They cannot live with a foot in each world choosing from the old and new covenant the parts which seem to hem more attractive. If they want to be Jews then they are bound to the Torah in its entirety. If they are going to follow the new covenant in Christ then they must trust completely in it. But the bottom line is that they must make a choice.
Do we truly trust in Jesus Christ? Do we trust that his kingdom will come? Do we trust that in the end God wins? Do we trust that God's justice will prevail?
If we do, then why so much talk of stress?
