The lavish nature of God’s love is indicated by the fact that He, as Father, is the author of our being adopted as sons and daughters through Holy Baptism.
[Recall] the testimony of the martyrs. Hear the good news of St. Michael: Christ has conquered by His blood, and the Kingdom of God and His will shall, in fact, be done on Earth as it is in Heaven.
Indeed, baptism is life because resurrection is life. Nothing short of regeneration—renewal of life—is accomplished by God through sheer grace because of Christ Jesus.
Believers are reminded—and the preacher is to remind them—baptism marks the forgiveness of sins, the end of legal demands, justification and regeneration, and the ultimate triumph over rulers and powers.
Baptized believers are in Christ and of Christ. Once they were alienated from and hostile to God, now they have been reconciled through the work of Christ. This forgiveness is not unconditional. Christ is the condition and, indeed, He fulfills all the conditions.
The Father, then, “has qualified you” through the work of Christ to share in the family inheritance. This inheritance is the Family of God itself and the family of the triune God Himself.
