Every Sunday, we will be going through one of the fifty-two Lord’s Days of the Heidelberg Catechism. Written in the year 1563, the Heidelberg still remains a popular confession of faith in many churches to this day. You can find the full text here.
Lord’s Day 13
Question 33: Why is he called God’s “only begotten Son” when we also are God’s children?
Answer: Because Christ alone is the eternal, natural Son of God.1
We, however, are adopted children of God—
adopted by grace through Christ.2
1. John 1:1-3, 14, 18; Heb. 1
2. John 1:12; Rom. 8:14-17; Eph. 1:5-6
Question 34: Why do you call him “our Lord”?
not with gold or silver,
but with his precious blood—1
he has set us free
from sin and from the tyranny of the devil,2
and has bought us,
body and soul,
to be his very own.3
1. 1 Pet. 1:18-19
2. Col. 1:13-14; Heb. 2:14-15
3. 1 Cor. 6:20; 1 Tim. 2:5-6
Many kingdoms throughout history have faced rebellions. Some kings may have even lost a son in battle fighting for the kingdom against the rebellion. But how many kings on Earth would send their son to die in order to save some of the rebels? How many kings would pardon the death sentence for those rebels? How many would bring these rebels into their kingdom? Not as slaves or servants…but as sons and daughters?
This would be unheard-of for an earthly king, but this is what the God of the universe has done for us. This is the radical love of God, that He would send His Son, Jesus, to rebels and sinners.
That He would send Jesus here not to squash the rebellion by killing every last rebel, but to live the sinless life that they couldn’t and to spill His precious blood to pay a debt that they could not pay, all so they could enter His kingdom. Why do we call Him “our Lord”? Because He has bought us, body and soul, to be His very own. How can rebels be adopted as sons and daughters of God? Only by the grace of God and the precious blood of Jesus.
