Note, 1. It is by the word and prayer that our communion with God is kept up. God speaks to us by his law, and expects we should hear him and heed him; we speak to him by prayer, to which we wait for an answer of peace.
How reverent and serious should we be, whenever we are hearing from and speaking to the Lord of glory! 2. If God's word be not regarded by us, our prayers shall not only not be accepted of God, but they shall be an abomination to him, not only our sacrifices, which were ceremonial appointments, but even our prayers, which are moral duties, and which, when they are put up by the upright, are so much his delight.
See Isaiah 1:11. The sinner whose prayers God is thus angry at is one who wilfully and obstinately refuses to obey God's commandments, who will not so much as give them the hearing, but causes his ear to decline the law, and refuses when God calls; God will therefore justly refuse him when he calls.
See Proverbs 1:24.
