…And, my child, don’t say in your thoughts, "Why is this?" and, "Why is that?" The Lord’s judgments are an abyss. Glory to God because he loves us all. His love is manifest in our illnesses and our sorrows. "For my strength," He said, "is made perfect in weakness." (2 Cor. 12:9)
This love of Christ has also made me grieve and suffer with you. But do not fear temptation. It is a trial. God allows as much as He thinks is best, and in the end, His goodness will prevail.
Elder Joseph the Hesychast
