Nevertheless, when the Son of Man comes, will He really find faith on the earth (Luke 18:8)?
What is Faith? People often answer with something like this: Believing that God is our Father, Jesus paid for our sins with His blood, and the Holy Spirit guides us. However, the devil also believes that, so is he then a Christian? Of course not. Believing in the Trinity and their varied attributes is simply that: our belief system.
Matthew starts the study of faith in the New Testament by establishing that God does and will take care of His own. Trusting God to see to our upkeep is the beginning of faith.
