The Bible frequently uses the hyssop plant as a symbol of cleansing and purification. In relation to Christ's sacrifice, this herb has a connection to the Passover.
Bill Onisick asks us to imagine a hypothetical situation in which we picture ourselves as an olive grower in biblical times who contracts the horrible, wasting disease of leprosy. After confirmation of the symptoms from the high priest, we become isolated . . .
The leper's healing teaches that, while Jesus freely healed the man, his cleansing was not really free. The gift he was told to present contains vital instruction.
Joy and gladness are gifts from God, resulting from Christ living His life in us and helping us to love the brethren. This love is perfected through suffering.
The proponents of a 15th Passover discount clear scriptural details and instead speculate. One cannot build doctrines on implication, distortion, and traditions.
