Christ, the Sinners Advocate

What does infinite really mean? Can we ever know all there is about Christ? Is the Bible meant to tell us everything about God so that we can know Him completely? How do we see that Christ's cry of victory is the crescendo of Psalm 119? How is Christ's cry 'it is finished' is the ultimate cry of victory? What is the Eternal Covenant? Why did God inspect His Lamb? Was Christ fully God and fully a man? Why was Christ of a different line of Priest than Aaron? Is Christ in heaven still bearing our sin? Why should we consider our flesh dead, mortified?
