Christians need to remember why Jesus came and what He did for all people - if they choose to follow Him. We need to remember that we go to church/worship to honor Him. And we should never expect other Christians to be "perfect" human beings and flawless.
Christians should recognize God for who He is. God has standards of how Christians should behave and live. Sadly, even the most dedicated faulter. We need to be a people who repent. Repenting is a turning toward God and away from our wrong deeds and/or poor lifestyle choices.
Those of us who have been backsliding from our relationship with other Christians, studying Scripture, and/or God Himself need to return. How easy is it to say I'll just sleep in Sunday morning and find yourself eventually not going to church at all? How easy is it for someone to hurt your feelings and then become too proud to "deal" with those people anymore? How many of us have gone through traumatic experiences only to disown God for His, seemingly, lack of protection? We need to return to Him and know that eternity is eternal and that this earthly life is just a vapor.
