Be careful with whom you choose as your close friends. It is because bad company corrupts good character (1 Cor. 15:33b). Do your friends contribute to your growth. Does their life principles are in line with God's Word? Are they doing things that makes God happy?
Having a friend with good character can also help you grow and develop your personality. Once you are communicating with them or enjoying their presence everyday, you will somehow also acquire their type of character like a contagious disease. Look closer on their personalities and principles if it can affect you positively or not. Or, if anything happens bad to you, will they be there at your side no matter what? So, choose your friends wisely. It can have a great impact in your life.
Also, be that good friend to someone. Love them and pray for them. Speak blessings and encouraging words. It is indeed a great feeling that many people are loving you because of your great character and big heart. Be that person whom they consider as a good friend. A person that they never regret to choose.
