Objection. But if faith so naturally causes good works, then what is the reason that God’s people find it so difficult to be fruitful in good works?
I answer, 1. God’s people are fruitful in good works according to the proportion of their faith; if they are thin in good works, it is because they are weak in faith. Little faith is like small candles, or weak fire, which though they shine and have heat; yet but dim shining and small heat, when compared with bigger candles and greater fire. The reason that some people in Sardis had works that were not perfect before God was because they did not hold fast by faith to the Word that they had formerly heard and received (Revelation 3:1-3).
