You Have A Measure Of Faith!

Romans 12:3
3... God has dealt to each one a measure of faith.

As children of God, we should never say, "I don't have faith." To say this is to say God is a liar because the Bible already tells us that "God has dealt to each one a measure of faith".
Why then does the faith of some seem to be stronger than others? Well, faith is like muscles. We are all born with a measure of muscles. But some of us develop our muscles more than others. Bodybuilders, for example, exercise their muscles very regularly to make them grow bigger and stronger.

Likewise, your measure of faith grows when you feed and used it. Each time you hear or read God's Word, you are feeding your faith. When you confess God's Word and expect good things to happen to you, you are using it. And the more you use it, the more your faith grows.
So use your faith. You could start with headaches. When you have a headache, instead of taking painkiller, use your faith. Ask God for healing, and trust, and thank Him for the healing.
Now, don't get me wrong, there is nothing wrong with taking medicine. And if you have to go to the doctor, don't fee condemned either. Just start using your faith at a level you are comfortable with. If you need to go to the doctor, then go in faith, praying, "Abba Father, I am going to the doctor. I am asking You in Jesus' name to give the doctor wisdom to give me an accurate diagnosis. My trust is not in him but in You."

And when you take your medicine, don't just swallow the pills. In faith, say, "Lord, sanctify this medicine," because some medicine may have negative side effects. When you ask God to sanctify it, He blesses that medicine. And what will be developing in you, growing bigger and possessing your body until it is too widespread and too late to stop it is divine health!
Beloved, you have been given a measure of faith. Start using it, believing that it is this measure of your faith that causes you to draw from the inexhaustible power of a faithful and loving God towards you!
