The word, “FOR” is defined: (Strong’s) “a preposition of direction; forward to, toward, by the side of, near to; motion towards, or nearness. — (Webster’s) used to indicate the place someone, or something, is going to, or toward.”
The word, “IN” is defined: (Strong’s) “a primary preposition; to or into (indicating THE POINT REACHED or ENTERED), of place, time, or purpose.”
So, Luke 8:13 says, “…They believe FOR a while, but when their faith is tested, they abandon it.” Did you notice that when they believe FOR, they eventually abandoned their faith. I think it’s because they never really “owned” their faith, because they were going “towards” it, but never possessed it. If I am believing FOR my health, then it hasn’t arrived yet, I still don’t have it. It’s beyond my reach. However, if I believe “IN’ my health… the health I already have “by faith,” then that puts my faith in the present, in the now.” It means I’m trusting God, the One who, “calls into existence things that don’t even exist.” (Rom 4:17) Do you see the difference?
When you believe FOR something, you’re going towards that something… you hope you can eventually have it in your possession. When you believe “IN” something, that something has already arrived, by FAITH, you have it “IN” your possession!
Every day I apply this in my life using 3 John 1:2 which says, “Beloved, I pray that you may prosper IN all things and be IN health, just as your soul prospers.” For me, concerning MY body, I am not believing “FOR” health, I am believing “IN” health! The health God said we could have in 3 John 2. Some might say, “You’re in a wheelchair, fed with a feeding tube and barely have a voice… that doesn’t sound like someone IN health. So how can you say you’re IN health?” To that I would say, “I’m IN health” because God’s Word says He wants us to prosper IN all things and be IN health, just as our soul prospers. And since God wants me to prosper and be IN health, then I believe and declare that I’m prosperous and IN health. I’m calling into existence, things that don’t even exist. (Rom 4:17) No matter what I see in the mirror, I choose to look through the eyes of God and see my body whole, strong, and fulfilling His plan for my life.
