Ref: Acts 4:27-28.
The heart of the Bible is not an explanation of where evil came from, but a demonstration of how God enters into it and turns it for the very opposite—everlasting righteousness and joy. […]
[T]he most astonishing thing is that evil and suffering were Christ’s appointed way of victory over evil and suffering. Every act of treachery and brutality against Jesus was sinful and evil. But God was in it. The Bible says, “Jesus [was] delivered up [to death] according to the definite plan and foreknowledge of God” (Acts 2:23). The lash on his back, the thorns on his head, the spit on his cheek, the bruises on his face, the nails in his hands, the spear in his side, the scorn of rulers, the betrayal of his friend, the desertion by his disciples—these were all the result of sin, and all designed by God to destroy the power of sin. […]
[God’s] aim, through evil and suffering, was to destroy evil and suffering. “With his stripes we are healed” (Isaiah 53:5). Is not then the passion of Jesus Christ meant by God to show the world that there is no sin and no evil too great that God, in Christ, cannot bring from it everlasting righteousness and joy? The very suffering that we caused became the hope of our salvation. “Father, forgive them, for they know not what they do” (Luke 23:34).

Why does a good God allow evil and suffering? I don’t know. But I do know what the answer cannot be: it cannot be that He doesn’t care. Why? Because He stepped into human flesh and endured the same evil and suffering.
