The characteristics of prayer are clearly defined by Jesus. When you pray, he states, do not be obvious about it, but pray in secret. Do not feign to pray much, because it is not due to a multiplicity of words that your prayer will be granted, but your sincerity. Before praying, if you have something against someone, forgive that person, because your prayer will not be pleasing to God if it does not come from a heart purified of every sentiment contrary to charity. In short, pray with humility like the publican, and not with pride like the Pharisee. Examine your defects and not your good qualities, and if you compare yourself with others, look for what might be evil in you.
