I only knew Charles Kingsley from titles of some of his children's books (like Water Babies).
Some great sermons I discovered on Bible Hub. Excerpts:
"Those who die in the fear of God and in the faith of Christ do not really taste of death; to them there is no death, but only a change of place, a change of state; they pass at once into some new life, with all their powers, all their feelings, unchanged; still the same living, thinking, active beings which they were here on earth. . . . Rest they may -- rest they will, if they need rest. But what is their rest? Not idleness, but peace of mind. To rest from sin, from sorrow, from fear, from doubt, from care; this is true rest. Above all, to rest from the worst weariness of all -- knowing one's duty, and not being able to do it. "
"Death is not death if it kills no part of us save that which hindered us from perfect life. Death is not death, if it raises us in a moment from darkness into light, from weakness into strength, from sinfulness into holiness. Death is not death, if it brings us nearer to Christ who is the fount of life. Death is not death, if it perfects our faith by sight, and lets us behold Him in whom we have believed. Death is not death, if it gives us to those whom we have loved and lost, for whom we have lived, for whom we long to live again. Death is not death, if it joins the child to the mother who was gone before. Death is not death, if it takes away from that mother for ever all a mother's anxieties, a mother's fears, and lets her see, in the gracious countenance of her Saviour, a sure and certain pledge that those whom she has left behind are safe, safe with Christ and in Christ, through all the chances and dangers of this mortal life. Death is not death, if it rids us of doubt and fear, of chance and change, of space and time, and all which space and time bring forth, and then destroy. Death is not death; for Christ has conquered death for Himself, and for those who trust in Him."
