4 But God, being rich in mercy, because of the great love with which he loved us,
5 even when we were dead in our trespasses, made us alive together with Christ— by grace you have been saved—
6 and raised us up with him and seated us with him in the heavenly places in Christ Jesus,
7 so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. ESV
Not ourselves, not the church, not the preacher, not anything “But God…”.
“With these two words we come to the introduction to the Christian message, the peculiar, specific message which the Christian faith has to offer to us. These two words, in and of themselves, in a sense contain the whole of the gospel. The gospel tells of what God has done, God’s intervention; it is something that comes entirely from outside us and displays to us that wondrous and amazing and astonishing work of God which the apostle goes on to describe and to define in the following verses.”
