Knowing who we are in Christ is crucial to our practice of Christianity every day. In other words, it is crucial to our spirituality. If we don't know who we are in Christ, we will easily be discouraged by our failures. Our enemy, Satan, will always tempt us to doubt God's love. He will always whisper deceiving thoughts in our ears and, if don't know how to take captive such thoughts, our hearts will be filled with desolation leading to our spiritual defeat.
