For everyone has sinned; we all fall short of God’s glorious standard.
As believers we sometimes have a difficult time showing mercy unto others when they fall into sin because we ourselves forget where we came from. We forget the life we once lived and the things we once did. We sometimes forget that someone showed us mercy and took it upon themselves to restore us. We tend to forget at times that we too have sinned at one point. We allow our own hypocrisy blind us from showing the same grace we desire when others fall short.
When you see that a brother or sister has fallen remember that “all have sinned and fallen short of the glory of the Lord. Remember that the same God who had mercy on you is able to have mercy on them as well. Granted no one will tell you to watch a fellow believer as they single handed lay walk themselves into the pit of hell. But as a believer you are expected to draw people in with truth and compassion. Do not water down the truth to appease anyone’s emotions, however in speaking those hard truths make sure that there is compassion beneath and above it all. When you see someone struggling do not simply write them off assuming that they aren’t worth mercy. Remember that you were shown mercy and as such extend that mercy unto others when needed. Do not push away the ones struggling with sin, instead pull them in and point them to Jesus.
