God's Word is His will. And if His Word
says "He sent His Word and healed them."
Psalms 107:20; then it is His will to heal.

The same faith for salvation works for
healing. In fact, healing is part of salvation.
Only it has to be taken by faith just as His
saving will is taken by faith.

Do not apply any if's, and's or but's to His
Word. They are words of doubt and will
not bring healing or salvation.
