The Way, the Truth, the Life
1 "Do not let your (pl) heart be distressed; you believe into God and you believe into me.A Greek verb is ambiguous in the 2nd person plural between Indicative and Imperative, and since that form occurs in both clauses here, there are four possibilities—Ind. Ind., Ind. Imp., Imp. Ind., Imp. Imp. The choice is up to the translator, which is why you will find differences among the versions at this point. We have already been told, in John 6:64, that Jesus knew who did not believe; it follows that He also knew who did. He knew that the eleven believed, so it seems more likely to me that He spoke in the Indicative. He is appealing to them to be consistent with their belief.
27 "Peace I leave with you, my peace I give to you; it is not like the world gives that I give to you.The world can offer peace of a sort, for a time, with a price tag, but it’s an illusion. Do not let your heart be distressed or intimidated.Satan will certainly use the world to try to intimidate and distress us, but how we react is up to us. We can decide to "let the peace of God rule in our hearts" (Colossians 3:15).
