Grace in the Genealogy of Jesus

I read the story of Tamar and Judah in Genesis 39 tonight for BSF.  Tamar was a Gentile woman who married Judah's sons.  Long story short she ends up sleeping with her father-in-law dressed up as a prostitute. Judah is ready to have her burned but Tamar pulls out a few things given to her on the day of the trespass. Judah owns up to his sin and she gives birth to twins.  She like Ruth and Rahab are listed in the genealogy of Jesus Christ.  What grace of God to include these women in the Savior's line.

As I think about God's grace it truly is more immense than man can imagine.  We deserve nothing but eternal punishment for sin.  But God.  Ephesians 2: 4-8: "But God, being rich in mercy, because of His great love with which He loved us, even when we were dead in our transgressions, made us alive together with Christ (by grace you have been saved),  and raised us up with Him, and seated us with Him in the heavenly places in Christ Jesus,  so that in the ages to come He might show the surpassing riches of His grace in kindness toward us in Christ Jesus.  For by grace you have been saved through faith; and that not of yourselves, it is the gift of God..."

We are saved by grace and frankly we are sanctified by it too.  God works in us and He accomplishes the good work He started. Yet we are to obedient to the Lord and His Word. I think the inclusion of the Gentile women indicates God's love extends to all peoples at all times.  The Tabernacle and later the Temple had a court of Gentiles.  Any who spiritually thirsted were welcome. His grace is magnificent.  Once again it is truly amazing.
