In the first <em>chapter </em>of the first <em>epistle</em> of the apostle Peter, in the verse 6, there is a part that says "...you are in heaviness through <em>many temptations</em>." That also means <em>suffereing</em>. Then, in verse 7, he mentions "that the<em> trial of you</em>r <em>faith.</em>..though it be <em>tried with fire</em>, might be found unto praise and honor and <em>glory</em> at the appearing of Jesus christ". Finally in verse 8, he says "...joy unspeakable and full of<em> glory</em>."
The apostle Peter was formerly known as Simon , but named Peter by Jesus. He writes to Christians facing prosecution to not falter in their faith, but to rejoice in the belief of their salvation and future glory in eternity. He sees the ones who are prosecuted but keeping the faith as the “elected “ones and these “elected” ones are specially chosen by God.
