Not only should we fear God so much that we should be searching every thing we do for any hint of sin (Psalm 139:23-24, see below) but we as His followers, His children, need to examine our inactions! You do realize that we can sin in an omission of good in our life?!
My sister pointed out that this means if we see trash on the ground and don't dispose of it, that is sin, by default.
Omission of good in our lives is sin.
One can claim to know the Lord and indulge in worldly pleasures that pass so quickly, but can that one present himself as a holy sacrifice to the Lord? Let's replace worldliness with Godliness. Let's do good! How do we know if something is good?
Is your life filled with things that do not meet these requirements? Are you striving to make every aspect of your life fulfill Philippians 4:8?
Again, let's fear the Lord and strive to present ourselves holy in his presence!
