If we want to be faithful, effective evangelists, we need to have a strong spiritual life. First, this means that we have to pray daily. Prayer is to the soul, what air is to the lungs. To grow in holiness, we should gradually learn how to “pray constantly.” We also need to build into our lives spiritual disciplines to form a foundation for that growth. Rooting out sin is an important part of this, and it should take place in the context of our growing knowledge of God’s love for us. Holiness, in fact, is always a call to gradually deeper freedom, in God’s love, and so we should not be overly severe or inflexible with ourselves. Also, we are each called to be a saint in a unique way. When difficulties and feelings of discouragement come, we should not be surprised but persevere in prayer, knowing that God is equipping us for greater things through various trials. As evangelists, we should pay special attention to doing spiritual battle for souls, in imitation of the Crucified Lord Jesus.
