The Apostle Peter came to the assurance that only through Jesus came eternal life. In John 6:68-69 Peter said that not only did he believe in our Lord but was assured that He was the true Christ Who was the living God. I see in these verses the affirmation of a cognitive will and trust in Christ Jesus. One might guess that Peter not only believed and trusted in Jesus at the onset but reflected on his relationship to God different times. There were certain things in Jesus life and Personality that brought about His trust and total reliance on the Christ. Verse 69 appears to be something beyond an arbitrary act of God is selecting the apostolic band as a vehicle through who He could work His ministry and Divine will. God chose twelve to follow and love Him, but one remained in sin and rebellion. If people are not personally convinced that Jesus is the Savior of the world, they will take the walk that Judas traversed, a journey that will end at the Great White Throne Judgment. [Revelation 20:11]. Yes, Peter speaking for the twelve said, 'And we believe and are sure that Thou art that Christ, the Son of the living God.'
