Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting. (Galatians 6:7-8 KJV)
This is a law that cuts across both the physical and the spiritual , it is what you call a universal law, it works in opposite directions in fact it is unbreakable and unstoppable. If you understand the above scripture properly you will see that it is a big self deception if you somehow think you can circumvent it... God will not allow it. In the physical no one plants coco yam and expect plantain, it's that simple. Furthermore if you have few of coco yam and want more, the best way to go about it, is not to eat what you have but to sow it....simple. Complaining won't get you more, crying won't get you more, there is only one way to go about it, sow coco yam or do without.
Let's consider this law in divine healing. If you want to operate in divine healing either for yourself or to minister to others, you must take the seeds of divine healing (that is scriptures that pertain to divine healing) and sow it into your heart, meditate on them until they take root and start to bear fruit in your life. This is the first step. Nobody goes from zero to a hundred, everything takes time (Mark 4:26-29). I see people who have never withstood a headache in the past, all of a sudden want to rebuke cancer. Is this impossible? Of course it is possible , but it is better to kill your bear, slay your lion before facing Goliath, that was the difference between David and his brothers.
The second step, look for people that require healing and minister into their life. Don't forget whatsoever a sows he will reap. In fact the Amplified version of the bible says 'that and that only will he reap'. If you don't like what you are reaping change what you are sowing both into your life by what you meditate on and into others. Galatians 6:9-10, says there is no limit to sowing the right stuff, don't get tired the harvest will surely come, especially if you do it to the people of God, there is a special blessing attached to it.
But call to remembrance the former days, in which, after ye were illuminated, ye endured a great fight of afflictions; (Hebrews 10:32 KJV)
Expect opposition, the devil will fight you tooth and nail to dissuade you when you first start on this track, oh yes he will whichever way possible, but remember not even the devil can mock God, 'whatsoever a man sows ,he will reap' that's a law and it cannot be broken.
WHATSOEVER A MAN SOWS, THAT AND THAT ONLY WILL HE REAP!
