As God's child, you belong to Him. From head to toe; every part of you belongs to God, and should be used for His glory. However, though you belong to Him, it’s your responsibility to keep your body clean and healthy.
There are some people who get sick just because they don’t keep their bodies clean. Therefore, learn to always keep your body and surroundings clean.
For example, you should have your bath and brush your teeth properly. Also, when you're back from school, put away your dirty clothes properly and develop the habit of keeping your surroundings clean always.
Confession
I care for my body and my surroundings by keeping them clean!
