Do not be misled: "Bad company corrupts good character." 1 Corinthians 15:33
Parents always delight when their children choose good friends. While they are still under your roof from ages birth to 5, it is pretty easy to control friendships but once they enter the "world" it is up to you to pray and for them to choose wisely. This is not to say parents of young people should sit around fretting about relationships but indeed your job is to pray and keep praying. Even when the picture may look bleak God is not done yet.
Bad friends can lead youth into immoral activity, drunken binges, drugs, pornography, and a life of crime and take them away from their church upbringing. Many a heartbroken parent has wondered what happened and why their son or daughter chose what they did. God uses all things to draw us back to Him. Sometimes a person might have to be flat on his back before he bothers to look up to the Savior.
Do not be misled. You can not continue to live a life away from God and full of sin and get away with it. The lusts of the flesh may entice but my friend run fast and far away from them.
PRAYER: Lord I need you every hour. Lord I pray for those I may know who are disinterested in you. Lead them to the cross. In Jesus' name. Amen.
