If your hand or your foot causes you to sin, cut it off and throw it away. It is better for you to enter life crippled or lame than to have two hands and two feet and be thrown into the eternal fire.

They had dreamed of a temporal kingdom with external pomp and power, fastened upon Christ's words of glory while forgetting His sufferings. Many love to hear of privileges and crown while overlooking the yoke and cross.
