The atoning death of Christ is the fount of Christian thanksgiving.
The death and resurrection of Jesus Christ is lived out in the life of the Christian. We live in the in-between time, the time of sorrows. But this time of sorrow is limited. It will not last forever.
Just as most children find it easier to get along with their grandparents than with their siblings, we in the Church Militant find it easier to honor our fathers in the faith than the brothers who surround us.
The Church Militant is not only fighting with Satan and his demonic armies. It is also fighting with itself. Brothers fight.
The words of the familiar psalm are more than poetry. They are a confession of faith: With Christ as our Shepherd, we want for nothing.
