Question 64. But doesn’t this teaching make people indifferent and wicked?
Answer: By no means: for it is impossible that those, who are implanted into Christ by a true faith, should not bring forth fruits of thankfulness (a).
(a) Matthew 7:18: A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit.
For your personal reflection:
If the branch abides in the vine fruit is the inevitable consequence. The sap which flows through the vine makes both the branch alive and produces fruit. So it is with the believer. Those who have been grafted into Christ are made alive and will produce the fruit of this union. Even the thief on the cross bore fruit the moment he trusted Christ by witnessing to the other, unrepentant, thief.
If being grafted into Christ always produces good works in the life of the believer why then do some who profess Christ show not fruit?
