At the core of our faith is an impossible birth—the birth of the Lord Jesus to the virgin Mary. Clearly, as Gabriel told her when he announced the glorious news that she would bear the Son of God, nothing is impossible for God. This theme echoes the announcement to Sarah in Genesis 18, and it reemerges in Jesus’s conversation with Nicodemus in John 3 about the new birth. Truly, we can trust this God of the impossible to complete the good work in us and bring us safely into His presence in glory.
