Obedience unites us so closely to God that it in a way transforms us into Him, so that we have no other will but His. If obedience is lacking, even prayer cannot be pleasing to God.
It is clear that he does not pray, who, far from uplifting himself to God, requires that God shall lower Himself to him, and who resorts to prayer not to stir the man in us to will what God wills, but only to persuade God to will what the man in us wills.
The greater the charity of the Saints in their heavenly home, the more they intercede for those who are still on their journey and the more they can help them by their prayers; the more they are united with God, the more effective those prayers are. This is in accordance with Divine order, which makes higher things react upon lower things, like the brightness of the sun filling the atmosphere.
God answered the prayers of animals.
