When Christians worship God, their cultic activities display, in widely varying combinations, attitudes of fear, respect, love, trust, awe, deference and obedience. They worship the Lord with all their heart, soul and strength, confessing their own insignificance in comparison to God, yet expressing confidence in the divine mercy which they believe will assist them through the trials of this life, toward a joyful existence beyond the grave. In the liturgical churches, the dominating mood varies according to the tables of feasts and fasts: Christmas and Easter are times for joyful song, brightly coloured vestments and festive activities. Ash Wednesday and Good Friday are days of penitence, sorrow and sombre hymnody. (‘Remember, Oh Man, that dust thou art…’) Throughout the year, the houses of worship are places of bowed heads and lowered voices, of respect and sobriety, and sometimes of veneration for icons and the objects used in worship. The inventory of revered objects varies considerably, as do the activities thought to be appropriate in this connection, ranging from the Low Protestant's respectful handling of the Bible to the High Churchman's prostration before the Monstrance, in the Benediction of the Holy Sacrament. But it is clear that divine worship normally involves reverence and awe and that it usually involves some form of self-abasement (bending the knee before).
