Proclaiming the Excellencies of God

"That you may proclaim the excellencies of Him who has called you out of darkness into His marvelous light" (1 Pet. 2:9).

You are an ambassador of the living God.

The privilege of proclaiming the excellencies of God takes us back to 1 Peter 2:9, but we consider it here because it summarizes the purpose of all our Christian privileges.
The Greek word translated "proclaim" is an unusual word used only here in the New Testament. It means "to advertise" or "publish," and refers to making something known that would otherwise be unknown. "Excellencies" speak of powerful and heroic deeds. You are an ambassador of Christ, having the great privilege of proclaiming what God has done for His people.
That was an intrinsic part of Hebrew worship. For example, Psalm 103 says, "Bless the Lord, O my soul, and forget none of His benefits; who pardons all your iniquities; who heals all your diseases; who redeems your life from the pit; who crowns you with lovingkindness and compassion; who satisfies your years with good things, so that your youth is renewed like the eagle. The Lord performs righteous deeds, and judgments for all who are oppressed. He made known His ways to Moses, His acts to the sons of Israel. The Lord is compassionate and gracious, slow to anger and abounding in lovingkindness" (vv. 2-8).
It would be an honor to be an ambassador of the United States, representing this country's power and capabilities to other countries. But you have an even greater honor: to represent the power and capabilities of the living God. When you have an opportunity to speak for Him, you can rightly say, "I have the privilege of announcing the mighty and heroic deeds of the living God, who has called me into His service."
Because you are in Christ, you have glorious privileges that include union with God, access to the Father, spiritual sacrifices, security, affection, dominion, possession, holiness, illumination, and compassion. What greater honor can there be than to proclaim the excellencies of the One who has granted you such marvelous privileges?
Suggestions for Prayer

Thank God for calling you as His ambassador.

Ask Him for the courage and integrity to represent Him well always.
