Can you imagine Jesus hanging out in a bar? No. Sinners would search for Jesus and find Him in healthy places. Jesus did not seek out people having a good time in unhealthy places.
One problem with going to bars is that it encourages fallen fleshly appetites. Paul wrote, “Since we have these promises, beloved, let us cleanse ourselves from every defilement of body and spirit, bringing holiness to completion in the fear of God.” 2 Corinthians 7:1. Remember: we are the salt of the earth. Our words and conduct should bless and uplift people.
There are several scriptures which advise us to carefully select our friends and companions. Those with whom we keep company influence our thinking, actions, and characters.
Jeremiah 15:17 (NIV), “I never sat in the company of revelers, never made merry with them; I sat alone because your hand was on me and you had filled me with indignation.”
Psalm 1:1 (NIV), “Blessed is the one who does not walk in step with the wicked or stand in the way that sinners take or sit in the company of mockers.”
1 Corinthians 15:33 (NIV), “Do not be misled: Bad company corrupts good character.”
It would be best to develop friendships with other good Christians. We all help each other to fight temptations and to grow in Christ-likeness.
