Peter in his first epistle is going to tell us about living for Christ as pilgrims in a hostile land. He begins by reminding us that we have all the mercy we need to live victoriously through every situation of life.
Alexander Maclaren describes Christ’s mercy, “like water in a vase that takes the shape of the vessel that holds it. On the one hand, His grace is infinite, and is given to every one of us according to the measure of the gift of Christ with no limitation but His own unlimited fullness. On the other hand, the amount we practically receive from the inexhaustible store is determined by the measure and purity and intensity of our faith. On His part there is no limit but infinity; on our side the limit is our capacity; and our capacity is settled by our desire. His word to us ever is, ‘Be to us as we will!’”
In other words, by vibrant faith that comes through a strong relationship with Jesus, we can have as much of His great mercy as we want or need. Thank you Lord for Your great mercy!
