Everything happens according to the judgement of God

Elder Nikon of Optina
The Will of God

If you carefully observe the details of your life and that of others, with startling clarity you will see that no amount of caution or measure taken has ever been able to determine what will transpire, for everything happens according to the judgement of God. There is no one to blame. We must humble ourselves and endure, otherwise we sin against God.

[Living without Hypocrisy, p. 23]

Wholeheartedly rely on the will of God

Elder Nikon of Optina
The Will of God

If we wholeheartedly rely on the will of God, then everything will be fine, and what is unpleasant will be accepted like as it should be. Everything that happens leads to the salvation of our souls, and in this is revealed great and profound wisdom. To them that love God, all things work together for good (Rom. 8:28).
