Which Bible passages support this answer?

The Westminster Assembly attached these Scripture proofs to answer 29. Read them together and ask what each one shows about the answer.

1. John 1:11-12

   ¹¹He came to what was his own, but his own people did not receive him. ¹²But to all who have received him—those who believe in his name—he has given the right to become God’s children— (NET)

2. Titus 3:5-6

   ⁵he saved us not by works of righteousness that we have done but on the basis of his mercy, through the washing of the new birth and the renewing of the Holy Spirit, ⁶whom he poured out on us in full measure through Jesus Christ our Savior. (NET)

What does this answer mean?

Christ purchased redemption. This answer asks how it becomes ours. We become partakers of it when the Holy Spirit effectually applies it to us. Christ accomplished salvation, and the Spirit applies it to the people God saves. Both persons of the Trinity are at work: the Son purchased redemption, and the Spirit brings it home to each believer.

What can we ask our children?

1. Who bought our redemption?
2. Who applies it to us?
3. What do you think it means to 'partake' of something?
