[E]very tree each summer unfailingly puts forth at least one shoot of considerable size, and unfailingly grows in height and dimension. It seems as though every tree tries each year to advance by the strength that God has given it; therefore, say to yourself, ‘I, too, must each day, each year, absolutely grow higher and higher morally, better and better, more and more perfect; must advance on the road to the Kingdom of Heaven, or to the Father which is in Heaven, through the strength of our Lord Jesus Christ and His Spirit dwelling and working within me.’
–Saint John of Kronstadt (1829-1908)
