There are two types of people in this world: those who give up and those who press on in faith. One's life leaves a trail of evidence that shows whether they truly believe in God or doubt Him. Faith is the evidence of things unseen; one must walk by faith, not by sight, and allow God's Spirit to lead them rather than their flesh. Life presents obstacles, but through Christ one has the tools to overcome all challenges. One must not waver in their faith, resist the devil, and believe God's promises. To please God, one must walk by faith in Him and His word, not rely on their own understanding.
