Have you ever known someone who has always done what he or she says he or she will do? If you're a Christian, you know Someone! As Christians, we know that Jesus Christ is always faithful to do what He says He will do.
Paul reminded the church at Thessalonica of this truth. After commanding the Thessalonians to rejoice, pray, be thankful, hold onto good things, and stay away from evil things, Paul reminds the Thessalonians that Jesus Christ is faithful.
Jesus is faithful not only to be with us as we hold onto good things and stay away from evil things, but He is also faithful to guide us through life. He will be there when we need Him to be, and He will help us to remain faithful to Him when difficulties arise.
In the end, we realize that there is no one who is more faithful than Jesus Christ. Once we realize this truth, we can live at peace, knowing that the God of the universe will not leave us, that He knows everything that we need, and that He is faithful to provide for us. He is faithful!
