The question of comfort is placed, and treated first, because it embodies the design and substance of the catechism. The design is, that we may be led to the attainment of sure and solid comfort, both in life and death. On this account, all divine truth has been revealed by God, and is especially to be studied by us. The substance of this comfort consists in this, that we are ingrafted into Christ by faith, that through him we are reconciled to, and beloved of God, that thus he may care for and save us eternally.
Concerning this comfort, we must enquire:
What is it?
In how many parts does it consist?
Why is it alone solid and sure?
Why is it necessary?
How many things are necessary for its attainment?
