Even the apostles did their healings by the power of Christ. Today, Christians are still being healed by the name and power of Christ through prayers and the laying on of hands with prayers to Christ. They are the possession of God. The bride of the Lamb. They can reach God direct through Jesus the Christ.
Believers are a holy nation.
Not any group of people separated from a nation of saints that are elite and different to themselves. Believers are living saints, not dead figures and statues. Peter did not mention other chosen race. There is but one chosen race of God, redeemed by the blood of Christ. The bible does not talk of any other redeemed group.
