The term "mortally ill" refers to a condition of severe illness that is expected to lead to death. In the biblical context, instances of mortal illness often serve as pivotal moments for divine intervention, expressions of faith, or demonstrations of God's sovereignty and compassion.

Biblical Instances:

1. Hezekiah's Illness:
One of the most notable accounts of mortal illness in the Bible is that of King Hezekiah. In 2 Kings 20:1 , it is recorded, "In those days Hezekiah became mortally ill. The prophet Isaiah son of Amoz came to him and said, 'This is what the LORD says: Put your house in order, for you are about to die; you will not recover.'" Hezekiah's response was one of fervent prayer and repentance, and God extended his life by fifteen years (2 Kings 20:5-6).

2. Lazarus:
The account of Lazarus in John 11 is another profound example. Lazarus was gravely ill, and despite the pleas of his sisters, Mary and Martha, Jesus delayed His visit. Lazarus died, but Jesus declared, "This sickness will not end in death. No, it is for God’s glory so that God’s Son may be glorified through it" (John 11:4). Jesus later raised Lazarus from the dead, demonstrating His power over life and death.

3. The Woman with the Issue of Blood:
In Mark 5:25-34, a woman suffering from a chronic illness for twelve years approached Jesus in faith, believing that touching His garment would heal her. Though not explicitly described as "mortally ill," her condition was severe and debilitating. Her healing illustrates the power of faith and Jesus' compassion for the suffering.

Theological Implications:

· Divine Sovereignty and Compassion:
The accounts of mortal illness in the Bible often highlight God's sovereignty over life and death. They also reveal His compassion and willingness to intervene in human suffering. The healing of the mortally ill serves as a testament to God's power and mercy.

· Faith and Prayer:
The response to mortal illness in the biblical narrative frequently involves prayer and faith. Hezekiah's prayer and the faith of those who sought Jesus' healing power underscore the importance of turning to God in times of dire need.

· Eternal Perspective:
While physical healing is a significant theme, the Bible also emphasizes an eternal perspective. The temporary nature of earthly life is contrasted with the promise of eternal life through faith in Jesus Christ. As Paul writes in 2 Corinthians 4:17-18 , "For our light and momentary affliction is producing for us an eternal glory that is far beyond comparison. So we fix our eyes not on what is seen, but on what is unseen. For what is seen is temporary, but what is unseen is eternal."

Practical Application:

Believers are encouraged to seek God's guidance and healing through prayer when faced with mortal illness. The biblical accounts serve as reminders of God's ability to heal and His ultimate control over life and death. Christians are called to trust in God's plan, whether it involves miraculous healing or the grace to endure suffering with hope in eternal life.
