Deuteronomy 14:2 ... You are a people holy to God, your God. He has chosen you to be a people for Himself, a special treasure above all the peoples who are on the face of the Earth.
Exodus 19:5,6 ... If you will listen obediently to what I say and keep My Covenant, you'll be My special treasure. The whole Earth is Mine to choose from, but you're special, a kingdom of priests, a holy nation.
God is speaking to Israel here, but in this time, we, as believers, are included, since being born again, we are made Abraham's seed. Just in case, you may think that these words are for the Jewish people ONLY, the following Scripture in the NEW TESTAMENT is for us also, as believers.
Titus 2:11-14 (The Message Bible)... God's readiness to give and forgive is now public. Salvation is available for everyone! We're being shown how to turn our backs on a godless, indulgent life, and how to take on a God-filled, God-honoring life. This new life is starting right now, and is whetting our appetites for the glorious day when our great God and Savior, Jesus Christ, appears. He offered Himself as a Sacrifice to free us from a dark, rebellious life into this good, pure life, making us a people He can be proud of, energenic in goodness.
