It is easy for us as humans to cast judgement on people who we deem as flawed or not behaving in a Christian manner. When we see someone not living by, or shall I say, not heeding to the word of God we tend to turn our noses up...not outwardly all the time, but sometimes it's inward. It is at this point that we have instantaneous amnesia and forget we ourselves are yet flawed in some area of our lives. All of us are or have been struggling with something. Some have been delivered from deeply rooted sins, temptations that almost consumed us. The Bible says all have sinned and come short of His glory. 

Just because your fellow brother or sister has an area(s) of weakness that you don't struggle with does not give authorization for judgement. As Christians we should hold our brethren up and pray with them...not at them. We are more sensitive to others who struggle with those same areas we once did. It is through the tests, deliverance, and trials of time that compassion for others is birthed out of us. Jesus had compassion for the people. He was/is touched with our infirmities because he knows the struggles we have within. How? Because the bible says He was tempted in every way. So, if the Son of God was tempted and had to struggle against the enemy, we should arm ourselves in the same manner. We should not be so ready to judge others for their wrongdoings. Pray for them and love them as Jesus does with us in our struggles.
