Where there is God, there is no evil. Everything coming from God is peaceful, healthy and leads a person to the judgment of his own imperfections and humility.
God shows us His love for man not only in those instances when we do good, but also when we affront Him with our sins and anger Him. With what longsuffering he bears our lawlessness! "Do not call God a rightful Judge," says St. Isaac, "for His rightful judgment is not seen in your deeds. True, David called Him a righteous judge and rightly, but the Son of God has shown us that God is good and merciful even more. Where is His righteous judgment? We were sinners, but Christ died for us" (St. Isaac the Syrian, Word 90).
St. Seraphim of Sarov
