As Christians, we should live with purpose rather than fear death. Sickness is not always an indication of sin or spiritual failure, and healing is not a reward for strong faith. that some people, even His most loyal workers, are not healed by God.
Another unsettling reality is that death is inevitable.
The Bible states that "it is appointed unto man once to die, and after this comes judgement" (Hebrews 9: 27). However, a lot of Christians live in continual terror of dying and worry about what could happen. Jesus came to deliver us from that terror.
We don't have to worry about what the enemy might do. "Don't be afraid of those who can kill your bodies but not your souls," declared Jesus. Only God, who has the power to annihilate both the body and the soul in hell, should be feared. Matthew 10:28–30 states that "not a single sparrow can fall to the ground without your Father knowing it, and the very hairs of your head are all numbered."Nothing can happen to you without God's consent if you give your life to Him.
Therefore, instead of worrying about the devil or questioning God's ability to heal, concentrate on leading a moral life, believing in God's plan, and praising Him in every circumstance.
