The Word of Prophecy

The word of prophecy is Jesus Christ. If we're going to have a clear look at the future, we have to look at it through the lens of Jesus Christ. Our conquerer, our king, our lord. The one who will establish his kingdom forever. "And behold, One like the Son of Man, coming with the clouds of heaven. Then to Him was given dominion and glory and a kingdom, that all peoples, nations, and languages should serve Him. His dominion is an everlasting dominion, which shall not pass away, and His kingdom the one which shall not be destroyed" (Daniel 7:13-14). Solomos asks about losing salvation as it concerns Judas and King Saul.When it says repent of your sins (plural) is that referring to behaviors?
