Gregory of Nyssa

This is the grace of the Holy Spirit, possessing the entire soul and filling the dwelling place with gladness and power, making sweet for the soul the sufferings of the Lord, and taking away the perception of the present pain because of the hope of the things to come.

For this is the grace of the Holy Spirit, possessing the entire soul and filling the dwelling place with gladness and power, making sweet for the soul the sufferings of the Lord and taking away the perception of the present pain because of the hope of the things to come. So, govern yourselves thus as you are about to ascend to the highest power and glory through your co-operation with the Spirit; endure every suffering and trial with joy with a view toward appearing to be worthy of the dwelling of the Spirit within you and worthy of the inheritance of Christ. Never be puffed up or enfeebled by indifference to the point of falling yourselves or being the cause of another's sin.
