By carnal love is not meant sensual love, but false love among the pious. God, in His grace, permits even a downpour of bitter, unrighteous rebukes and an icy, loveless north wind to beat upon love's edifice. The poorly-built house falls together with a crash that is heard far away. Where one ceases to love with the love of Christ, there unrighteousness, confusion, and death, are the inevitable result. And to love in God's way can be learned only in the school of the Lamb.
Love is obedience.
For many, this is a burning question. He who loves God will by his love bind men to God, not to himself. John rejoiced when his disciples left him and followed after Jesus, because he loved Jesus. Such a love conquers at last and is understood, even if throughout all its life it may have been regarded as harshness. Every friendship which does not rest upon this foundation is enmity.
