If you're a teacher, always try and give some thought as to how you want to end the class. You can't teach well unless you ended well. In teaching, motivation is such a crucial factor. Determine never to end class on a negative note. Always conclude with a word of hope and encouragement. Let your students know that you are for them. You want them to do well, and you are always available to help them succeed. You can even plan your closing prayer so that it ties up loose ends.
Let's make it a point to conclude with Jesus honored at the end.
