Re∣member the Sabbath day, to keep it holy, Exod. 20. 8 So I may say, remember Prayer, to keep it holy; remember Meditation, to keep it holy; remem∣ber all the duties of Religion, to keep them holy, and perform them in an holy manner: think of them before you go about the performance of them; we cannot pray unless we watch un∣to prayer, unless we be careful, and have our eyes in our heads, before we go about the du∣ty.In the morning as soon as we awake, we should think of prayer; and when tempted to sin, we should think of prayer. If I sin, how can I pray unto God? I have ever and anon need to poure out my prayers before God; now if I commit these and these sins, how can I look up to heaven, when my conscience doth reproach me for sin? So when we hear the word of God, look to thy foot when thou comest into the house of God, Eccles. 5. 1. that is, Before thou goest into the House of God to hear the Word of Salvati∣on, see into thine own heart, think whose word it is thou hearest; and that thou goest to hear the Word, that shall judge thee at the last day. When thou comest into the presence of God, take heed lest thou hearest as fools hear; and take heed lest thou prayest as fools pray; and comest to the Sacrament, as fools use to come; we should watch before the duty, that all things may be in a readinesse, before we come to the performance 0
