I love the challenge of teaching mathematics to high school students. It is very rewarding to help them see how all of the concepts work together to form a picture. What a wonderful order the Lord has created that allows numbers to explain so much.
John 10:27-28 My sheep hear my voice, and I know them, and they follow me. 28 I give them eternal life, and they will never perish, and no one will snatch them out of my hand.
