BIBLE READING: HEBREWS 11:8-12
Hebrews 11: By faith Sarah received strength to conceive.
Consider the words used in Hebrews 11:11, Sarah received strength to conceive. How did she receive the strength that enabled her to get pregnant. Obviously, we know God didn't come from heaven to lay hands on her, neither did a prophet do it. In reality, Sarah received strength from the spoken word of God. Her strength to conceive, carry and give birth to Isaac came from the spoken word, the word God gave her. He promised to give her a child.
Once Sarah accepted the words in faith, they produced strength in her body. It brought back to life her dead egg cells and womb. The same words also enabled her to carry the baby and push it out at the age of 90. As long as Sarah doubted the promise, she wasn't able to conceive but once faith rose in her, life entered into her body. In the same way if you believe the promises of God for your life, you will experience strength in that area.
Jesus himself said that the words he speaks are spirit and life. No matter the sickness you are facing, receive the word of healing by faith and watch sickness fly away from you.
