Very interesting, as evidences of the heartfelt piety of the early converts, are the letters which many of them wrote to Yate on the eve of his journey to England. There is surely nothing of a merely conventional goodness about such language as this: "I have this day, and many days, kneeled down, and my mouth has whispered and has said loud prayers; but I wish to know, and am saying within me, if I have prayed with my heart. Say you, if I have prayed to God with my heart, should I say No, and not do His bidding, as the Bible says we must and tells us how? And should I flutter about here like a bird without wings, or like a beast without legs, or like a fish whose tail and fins a native man has cut off, if I had love in my heart towards God? Oh! I wish that I was not all lip and mouth in my prayers to God. I am thinking that I may be likened to stagnant water, that is not good, that nobody drinks, and that does not run down in brooks, upon the banks of which kumara and trees grow. My heart is all rock, all rock, and no good thing will grow upon it. The lizard and the snail run over the rocks, and all evil runs over my heart." The anxious and self-accusing spirit which appears in this passage deepens as the soul passes under the awe of the sacramental presence. "My Teacher," writes another, "I have been many moons thinking about the holy feast which Jesus Christ gave to His disciples, and told everybody to eat it in remembrance of Him. It is not a natives' feast; for in New Zealand everybody eats as much as he is able, and as fast as he is able; but this is a feast of belief. If my body were hungry, I should not be satisfied with a piece like a crumb, nor with a drop that will go in a cockle shell; but my soul is satisfied, my heart is satisfied, though it be a crumb and a drop. The thoughts within me yesterday were perhaps right, and perhaps wrong. I said to myself, I am going to eat and to drink at a table placed before us by the Great Chief of the world. I must be very good, and must make myself good within; or, when He sees me, He will show that He is angry. And then I thought, I will not think anything that is not right, nor do anything that is not straight to-day; and then, God will see that my heart is becoming good. But, Mr. Yate, perhaps you will, and perhaps you will not, believe it: I thought no good thoughts, and I did no good works all day; and yet I was still, and not angry with myself, no, not at all. Now, my Teacher, you say what I am to do, before the next day of the Lord's Supper. I think I must pray to God for a new heart, and for His Holy Spirit."
