Help the Church Instead of the World
Why don't we who are Christ's Church need to help the World? Because, on the one hand, they are given to their own ways, and on the other hand, God protects us from their ways. They are the enemies of God, and our willpower cannot change that, but He is our High Tower and our Fortress, in Whom we stand and in Whom we abide and have life.
Help the siblings. They can change and they can understand.
