He 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 Holy Spirit, whom He poured out on us in full measure through Jesus Christ our Savior. And so, since we have been justified by His grace, we become heirs with the confident expectation of eternal life. Titus 3:5-7 NET
Mary makes it seem so easy. The angel Gabriel tells her that she’ll give birth to the Son of God, and she responds with immediate surrender to her role in God’s plan. What was Mary thinking? She had no assurance of a comfortable outcome. A virgin engaged to be married, she likely knew how difficult giving birth to and raising Jesus would be.
The only assurance Mary received was God’s Word, and it was enough for her to say “yes.”
In 1 Peter 1, the apostle Peter says that through the trials we face, the genuineness of our faith is revealed.
