Just to pick out one of many problems with this:

“Here’s a gift and here’s what you have to do to keep it” isn’t good news for sinners who cannot do “their part,” not even with the help of grace.

Then we must not tell sinners to repent and believe the Gospel. Requiring faith is now Roman Catholic legalism in the mouths of our revisionist accusers of the Brethren.

Here’s my theology; if this be heresy make the most of it:

Q. 152. What doth every sin deserve at the hands of God?
A. Every sin, even the least, being against the sovereignty, goodness, and holiness of God, and against his righteous law, deserveth his wrath and curse, both in this life, and that which is to come; and cannot be expiated but by the blood of Christ.

Q. 153. What doth God require of us, that we may escape his wrath and curse due to us by reason of the transgression of the law?
A. That we may escape the wrath and curse of God due to us by reason of the transgression of the law, he requireth of us repentance toward God, and faith toward our Lord Jesus Christ, and the diligent use of the outward means whereby Christ communicates to us the benefits of his mediation.

Q. 154. What are the outward means whereby Christ communicates to us the benefits of his mediation?
A. The outward and ordinary means whereby Christ communicates to his church the benefits of his mediation, are all his ordinances; especially the word, sacraments, and prayer; all which are made effectual to the elect for their salvation.
