The God of all the things. The one who spoke the universe into existence and who sustains the worlds in their orbits. This God has shown his love for sinners in the person and work of Jesus Christ.
There is nothing that can capture the magnitude of this kind of love. How could there be? Even as a father, my love for our children pales in comparison to the love of God for those he sent Jesus to save.
We see grace in Christ, but what drives this grace to express itself in our fallen and sin-sick world? It is the heart of God to redeem and to save. The heart of God is on full display in the sacrifice of Jesus on the cross. The heart of God is heard in the simple proclamation of the Gospel of Jesus.
A holy God has stepped out of heaven and called all sinners to repentance. And, if we put our faith, hope, and trust in Jesus, the Messiah of God, we will be adopted and saved from the just penalty of our sin! Our trajectory will have been diverted from hello and eternal separation from God and set toward heaven and eternal joy in God.
I will probably never know what motivates the God described in the Scriptures. But I have no doubts about his love. I have no doubts about his mercy. I have no doubts about his grace. I have seen too much. Experienced too much. Learned too much to turn my back on him.
