¹³ Now all has been heard;
    here is the conclusion of the matter:
Fear God and keep his commandments,
    for this is the duty of all mankind.
¹⁴ For God will bring every deed into judgment,
    including every hidden thing,
    whether it is good or evil.

There are people who live in sin as if it's no  big deal. It may seems so, but the Word of God tells us something completely different."We die only once, and then we are judged" (Hebrews 9:27). 

Ecclesiastes 12 - Song of Songs 2.

May the Lord richly bless you!
