I like this description of the life in Christ that Martineau presents. When sharing my faith, this is the direction that I like to take, and letting the person know that they need not fear, Christ is living and will speak to the heart for Himself when earnestly sought.
"We must remember, that religion is after all beyond the range of mere tuition. It is not a didactic thing that words can give, and silence can withhold. It is a spirit; a life; an aspiration; a contagious glory from soul to soul; a spontaneous union with God. Our inward unfaithfulness is sure to extinguish it; our outward policy cannot produce it. To love and to do the Holy will is the ultimate way, not only to know the truth, but to lead others to know it too." James Martineau.
