Elder Paisios on those who suffer for the world

An icon depicting St. Paisios receiving pilgrims, taking up their burdens and preaching to them the Word of God. His scroll reads: "We must struggle with philotimo, that we may be saved, and so that we not sadden Christ..." (source)

Those who suffer deeply for the salvation of the whole world and help in their own way (as strugglers) and humbly entrust themselves to the hands of God, feel the greatest joy in the world. Their life is a constant doxology, for they flutter about internally like angels, glorifying God day and night. Those, however, who neglect the salvation of their souls and try to find joy and rest in this vain life, are continually tortured and entangled in endless worldly machinery and live in hell in this life...Those who have philotimo, because they move within the heavenly sphere of doxology, joyfully accept their trials as well as their blessings, and glorify God for them. Thus, they are continuously receiving God’s blessing from everything and are melting internally out of gratitude towards God, which they express in every spiritual way possible, like children of God.
