The world we live in is a crazy place. Especially for teens. We struggle with, swearing, gossip, sexuality, rudeness, sex, drugs, alcohol, depression, suicide, and so many other things. The great thing though is that God is always with us. Not just as an innocent bystander who judges everything you do, but also as a friend, and a protector. God can get us through our teenage years (look at how many adults there are), and He can protect us from all of the negative, and often dangerous influences out there. If our God beat the Devil imagine how easy it could be for him to protect you in every day problems. All we have to do is let God do what He wants, and live how he wants. If we do that we cannot go wrong.
Romans 8:28 — And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
