Repent Now or Cry Later

Ecclesiasticus 5:6-7
[6]And say not His mercy is great; he will be pacified for the multitude of my sins: for mercy and wrath come from him, and his indignation resteth upon sinners.
[7]Make no tarrying to turn to the Lord, and put not off from day to day: for suddenly shall the wrath of the Lord come forth, and in thy security thou shalt be destroyed, and perish in the day of vengeance.
