" The Lord is not only tender and merciful and full of compassion, but He is also the God of justice, holiness and wrath…Compassion is not complete in itself, but must be accompanied by inflexible justice and wrath against sin and a desire for holiness. What stirs God most is not physical suffering but sin. All too often we are more afraid of physical pain than of moral wrong. The cross is the standing evidence of the fact that holiness is a principle for which God would die. God cannot clear the guilty until atonement is made. Mercy is what we need and that is what we receive at the foot of the cross. "
