Note 37 at Joh 14:27: Peace is something that can be given (Mt 10:13 and Lu 10:5-6).

Note 38 at Joh 14:27: Jesus distinguished His peace from what the world calls peace. In the world's mentality, peace is the absence of problems. However, God's peace is not dependent on circumstances. It is dependent only on God Himself who is the same yesterday, today, and forever (Heb 13:8). Christians can have great peace even in the midst of terrible problems because their faith is in God. "Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee" (Isa 26:3).

Note 39 at Joh 14:27: As in Joh 14:1 (see note 2 at that verse), "you" is the understood subject of this sentence, "Let not your heart be troubled, neither let it be afraid." That means that the responsibility of not letting our hearts be troubled is ours. Jesus has given us His peace, but we have to receive it by faith to keep our hearts from being troubled.

Note 40 at Joh 14:27: Most people identify with fear in certain situations and think it only normal. However, God did not give us the spirit of fear (2Ti 1:7), and Jesus' command here shows that we have the power to reject fear.
