To know about Christ is not enough. To be convinced that He is the Saviour of the world is not enough. To affirm your faith in Him, as we do in the Apostle’s Creed, is not enough. You really don’t actively believe in Christ until you make a commitment of your life to Him and receive Him as your Saviour.
Stop being angry! Turn from your rage! Do not lose your temper—it only leads to harm.
The New Living Translation
