Dear Brethren,
In case you have been struggling to get answer to this question, read what the Bible says concerning a just man or woman. You know that the Bible is our daily living manual, so let's try to explore Psalms 1:1, to have a knowledge of what it is to be just;
To be just is to walk not in step with the wicked or stand in the way that sinners take or sit in the company of mockers. Someone may be asking again, does it mean, I have to chase away those my friends who are ungodly? No, that is not it. Rather, it means that you should not take any bad advice they give you like, telling you that remaining a virgin before marriage makes you a lay girl or telling you that any man who doesn't smoke nor chase after girls is not man enough, or telling you to go partying instead of going to His sanctuary or may be telling you to lie to your parents/sponsor in order to get more money from them or telling you to either give or receive bribe to achieve a fit or telling you to blackmail someone so as to tarnish the person's image. These are to mention but a few.
Don't take such advice because they will make you unjust and lead to destruction too. If you know that continuing with such a friend will keep you vulnerable to the prey of satan and probably you have tried your best to keep such a friend in the faith, yet no positive result forthcoming from such, then do well to flee from him/her. As you have read from the above Bible verse, bad company ruins good manner.
Remain blessed,
Your beloved sister,
Ifeoma
