Proverbs 28:13-14

He who conceals his transgression will not prosper, but whoever confesses and turns away from sins will find compassion and mercy. Blessed and favored by God is the man who fears (sin and its consequences) at all times. But he who hardens his heart (and is determined to sin) will fall into disaster.  

Connecting to Proverbs, pride is a life stopper. When we humble our hearts and confess our sins, we can continue to flourish under the love of God. If we conceal our sins and refuse to acknowledge them and repent, we do not fear God or the consequences of our actions. Disaster will come because we refuse to acknowledge the error of our ways.
