The Bible does not specifically address the question of whether demons can give Christians or anyone else cancer. However, it does provide principles about the nature of suffering, the spiritual realm, and God’s sovereignty.

Firstly, Scripture acknowledges the existence of evil spirits and their influence on the physical world. For example, in the Gospels, Jesus healed many who were oppressed by demons (Acts 10:38). However, these accounts primarily involve possession and torment rather than specific illnesses like cancer.

It’s essential to distinguish between the broader biblical understanding of suffering and the specific causes of diseases. The Bible teaches that all creation is under the curse of sin, which entered the world through Adam and Eve’s disobedience (Romans 5:12). As a result, the world is filled with suffering, including diseases, but not every sickness is directly caused by demonic activity.

James 5:14-15 offers a response to illness in the community of believers: “Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord. And the prayer of faith will save the one who is sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven.” This passage encourages prayer and faith in God’s healing power, regardless of the sickness’s origin.

Furthermore, Romans 8:38-39 assures us of God’s love and presence in our struggles, stating, “For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.” This includes the trials of health, like cancer.

In summary, while the Bible does not explicitly state that demons can cause cancer, it acknowledges the reality of spiritual warfare and the impact of sin on creation. Believers are encouraged to seek God’s presence, healing, and peace in the midst of suffering, trusting in His sovereignty and love.
