A lot of people treat the matter of holiness as an expired topic or as an optional thing. This is not true. Holiness is a command from God. It is the nature of Saints, which is what we become when we get born again.
Before God destroyed Sodom and Gomorrah He removed the righteous first. Before He destroyed the first world, He preserved Noah and his family because they were righteous. Before God destroyed the city of Jericho He preserved the only woman who believed, Rahab and her family. God will not destroy the righteous with the wicked. This is why He warns His people to come out of the world, and not be a part of the corruption in the world. Though we live in the world we are not of this world. Let us live like pilgrims who have eternity in view.
“Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us, 2 Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God. 3 For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds. 4 Ye have not yet resisted unto blood, striving against sin.” Hebrews 12:1-4 KJV
When Jesus Christ called His Disciples they were so committed that they left everything and followed. They were so dedicated and faithful to their call, except Judas Iscariot. We are also being enjoined today to follow Jesus Christ with the same level of faithfulness.
Our stay in this world is actually for business. We are here to transact business, but not many people are aware. The gifts (talents) we have been given are for business. We shall all give account and receive our rewards on the Last Day. This message is a call to duty.
