Thematic Bible: Not being troubled

Jesus answered them, Do ye now believe? Behold, the hour cometh, yea, is come, that ye shall be scattered, every man to his own, and shall leave me alone: and yet I am not alone, because the Father is with me. These things have I spoken unto you, that in me ye may have peace. In the world ye have tribulation: but be of good cheer; I have overcome the world.

Jesus answered and said unto him, If a man love me, he will keep my word: and my Father will love him, and we will come unto him, and make our abode with him. He that loveth me not keepeth not my words: and the word which ye hear is not mine, but the Father's who sent me. These things have I spoken unto you, while yet abiding with you. read more.
But the Comforter, even the Holy Spirit, whom the Father will send in my name, he shall teach you all things, and bring to your remembrance all that I said unto you. Peace I leave with you; my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be fearful.
