God uses real people with problems to become part of the greater story of redemption, the birth of Jesus Christ.
Hebrews 4:14-16,14 Therefore, since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession. 15 For we do not have a high priest who cannot sympathize with our weaknesses, but One who has been tempted in all things as we are, yet without sin. 16 Therefore let us draw near with confidence to the throne of grace, so that we may receive mercy and find grace to help in time of need.
Romans 8:28-30, “28 And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose. 29 For those whom He foreknew, He also predestined to become conformed to the image of His Son, so that He would be the firstborn among many brethren; 30 and these whom He predestined, He also called; and these whom He called, He also justified; and these whom He justified, He also glorified.”
