The Watchman MUST Warn

PM sermons are preceded by a Confessional, Catechism, Historic Creed lesson, or a lesson from the NT (Usually 5 minutes or so) Canons of Dort 3rd & 4th Heads of Doctrine, Article 8: The Earnest Call of the Gospel
Nevertheless, all who are called through the gospel are called earnestly. For urgently and most genuinely God makes known in the Word what is pleasing to him: that those who are called should come to God. God also earnestly promises rest for their souls and eternal life to all who do come and believe.

Article 9: Human Responsibility for Rejecting the Gospel
The fact that many who are called through the ministry of the gospel do not come and are not brought to conversion must not be blamed on the gospel, nor on Christ, who is offered through the gospel, nor on God, who calls them through the gospel and even bestows various gifts on them, but on the people themselves who are called. Some in self-assurance do not even entertain the Word of life; others do entertain it but do not take it to heart, and for that reason, after the fleeting joy of a temporary faith, they relapse; others choke the seed of the Word with the thorns of life's cares and with the pleasures of the world and bring forth no fruits. This our Savior teaches in the parable of the sower (Matt. 13).
