Proverbs 28:13 (KJV) 13 He that covereth his sins shall not prosper: but whoso confesseth and forsaketh them shall have mercy.
Hiding or concealing sin has an adverse effect or consequence: it causes some kind of failure. Conversely, confessing and forsaking sins has a positive or favorable consequence: mercy—withholding of corresponding punishment or penalty.
Instead of regarding or hiding sins in our hearts and being more concerned about effectively covering them to avoid being caught, we confess them quickly and sincerely. There may be discussions as to the extents of the meaning of “not prosper,” but regardless of anyone’s interpretation, we would like to avoid it at all cost. We sin—that alone is always heartbreaking as believers, why linger there?
For others to come to a point when they would rather cover their sins than confess them is a proof that they’re already treading a very dangerous ground in their Christian walk—it’s a clear indicator that there’s a part of their walk where they are already off-course—they’ve been derailed and need to do everything to get right back on track as quickly as possible. We don’t hold on to sin; we discard and throw away every sin from us because they weigh us down and sidelines us. We don’t want to miss out on anything that our good God has for us. We desire the prosperity He wants us to have.
The more we’re tempted to cover our sins, to sugar-coat them, the greater the need for us to get rid of them as quickly as we would a burning coal or a ticking bomb in our hands. Mercy is a better choice than failure. Some people feel like they get away with it because they’re still succeeding even as they continue secretly sinning. But they don’t know what much greater benefits the Lord would have poured out on them had they chosen to walk faithfully instead. Besides, there really is nothing hidden; men may not see everything, but God sees all things. He already declared that there’s nothing hidden that will not be revealed, and that our sins will find us out. Why risk it?
Truth be told: we don’t ever want to find ourselves with a slightest inclination of covering our sins. We’d rather live in His pleasure.
