Being born again, you’re one of a kind; you’re the carrier of eternal life, the indestructible life of God! You have a special purpose on earth, to set forth the wonderful deeds and display the virtues and perfections of Him who called you out of darkness into His marvellous light. This is what 1 Peter 2:9 above communicates. You’re a special breed; superior to Satan, sickness and infirmities, and not subject to failure or limitations.
Someone might be angry at you and say, "Who do you think you are, acting like you’re so special?" Square up and say, "I’m not acting like I’m special; I’m special and I know it."
God made you, not so you’ll be defeated or be a "nobody" in life, but that you’ll be the reflector of His glory—His beauty, grace, and excellence. You’re His best. James 1:18 says, "Of his own will begat he us with the word of truth, that we should be a kind of firstfruits of his creatures."
Take pleasure in your uniqueness, for no one else in the world is like you. You must therefore bless the world with all the treasures the Lord has deposited in you; be the best of you to His glory.
