A Baptism of Fire
They had received the negative, water; they were to receive the positive, fire. Water is not sufficient for natures such as ours. The Baptist pointed to a greater Baptist than himself. Jesus plunges the soul into a baptism of fire.
Fire cleanses. Ore may be mingled with earthly ingredients from which it is imperative to free it.
So our characters are full of impurities and earthly ingredients; but as they are brought into contact with the power of the Holy Spirit, these are eliminated and drop away, and we attain degrees of purity and love which otherwise had made us unserviceable to our dear Lord. Do not seek to rid yourself of these things as a condition of his gracious cleansing, but seek the baptism of the Spirit, and He will free thee; for He is like a consuming fire.
Fire illuminates. . . . When the Spirit comes in power to the soul, He teaches us to know God, and truth, and things hidden from the wise and prudent. The fires that sanctify, illuminate us.
Fire enkindles. It is contagious. It will spread over an immense area, where inflammable material attracts it.
When the Spirit of God touches a soul, like an unlit candle, it begins to glow; and from it the blessed spark may pass from heart to heart, and church to church, till an entire continent may blaze with heavenly fire. (ODH) F.B. Myers, Our Daily Homily
Dear Lord, Yes, send the fire and begin in me.
