"For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge; and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness; and to godliness, mutual affection; and to mutual affection, love. For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ." (2 Peter 1:5-8 NIVUK)  Addition is the simplest skill a child is taught: 2 + 2 = 4. Similarly, "children" of God must strive every day to ADD good things to their faith. In this way, blessings in the Kingdom of Christ are multiplied many times, not divided nor subtracted from!
