And unto Adam [God] said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;

— Genesis 3:17

You must understand that God did not curse the earth.  God did not get so mad with Adam that He cursed his life, his wife, his labors, and the earth.  God created everything to be good, to multiply, and to be blessed.  Adam is the one who messed it up-–not God!  “Because you [Adam] have listened to your wife.”  “Because you [Adam] have eaten from the tree.”  “Cursed is the ground for your sake”!  Because of you, Adam, sickness and the curse have come into this world.  Because of you, Adam, spiritual death now rules over mankind.  Note that in verse 15, God began to prophesy a coming generation who would live in victory and walk on the devil’s head.  God is not responsible for the curse; He is not responsible for sickness and disease–-He is against the works of the enemy.  It is never God’s will that you be sick; He does not use sickness to teach you, nor to build character in you, nor to draw you closer to Him.  The thief comes to steal, kill, and destroy-–God came to give you life and life more abundantly (John 10:10)! God wants you healed (Acts 10:38)!  His desire is for you to prosper and be in health (III John 2).  Do not mingle God and the curse together.   He did not send it, desire it, or sanction it–-mankind chose it.

...by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:

— Romans 5:12

How did sin and sickness and the curse enter into the world?  Did God desire that man be under the curse?  If so, He could have said “Let Us make man cursed, sick, and diseased.”  Did God punish man with the curse?  No!  Sin and the curse entered the world by one man’s sin, Adam’s!  God told Adam how to stay away from sin and the curse-–“Do not eat...”  By one man sin entered into the world, and that sin gave way to the curse.  That sin and the curse passed upon all men because of Adam’s sin (read Romans 5:12 again).  How did depression, sickness, sin, and poverty get into the world?  By one man who sinned!  People have been wrongly taught that God will curse them or put sickness on them, but those are not God’s choices for man.  The curse is here, in this world, and you will choose to live under it or free of it!  Christ came not to curse you, but to redeem you from the curse, to offer you a protection plan so you could live in the blessing.  What kind of God would desire to curse you and redeem you at the same time?  Spiritual death came because of Adam, and it now rules and reigns over mankind (Rom. 5:17).  God created man to rule and reign, not to be ruled and reigned over!  The curse did not enter because of God’s anger toward man, but because of man’s disobedience toward God.  But in love, God gave us Christ, Who has redeemed us from the curse!

If thou wilt diligently hearken to the voice of the Lord thy God, and wilt do that which is right in his sight...I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the Lord that healeth thee.

— Exodus 15:26

God is not two-faced, double-minded, or schizophrenic.  He does not put sickness on you and then heal you, only to put sickness on you again.  The real meaning here in this verse is that God will “not allow” disease on you.  God has no choice, because spiritual death and the curse entered the world through Adam.  They reign over mankind.  Satan has a legal right over man.  God’s people have been under sin, sickness, and the curse.  So God offers them a protection plan, a hiding place from the curse.  Notice:  God says, “If you diligently hearken to My voice, if you do what is right in My sight, if you give ear to My commandments, I will be able to protect you!  I will not allow the curse to come on you.”  God is not saying, “Do this, and do that, or I’ll put sickness on you.”  He is saying “sin and the curse are in the world with a right to come on you, but if you hear the Word and do it, I will be able to override spiritual death, override sickness and disease!  If you do this, I will legally be able to keep you sickness-free!  Know this: ‘I am the Lord that healeth thee!’  I’m not the One Who is making you sick, I am the Healer!”  We have been taught He is the One Who makes us sick to teach us, makes us sick to keep us humble, makes us sick to punish us–-but He said, “I am the Lord that healeth thee.”  I believe we ought to believe who He says He is-–He is our Healing.

...I will put [allow] none of these diseases upon thee....

— Exodus 15:26b

God is offering His people a protection plan, an insurance policy, an umbrella, that will keep the curse from falling on them.  He has no union with sin, with spiritual death, or with sickness and disease.  He is the Lord Who heals you.  People will say “God didn’t put sickness on me, but He allowed it!”  God will allow you to rob a bank, commit sin, backslide, and not shower and stink, if you allow it!  God is not the only spiritual force in your life; there are angels and demons that exist.  You have a free will to operate in faith or fear, joy or sorrow, worry or peace.  You have a free will to choose!  God tells you to choose His Word, choose His voice, choose life and blessing.  But you can also choose the devil’s word, his voice, death and the curse.  You must choose, just like Adam, where you will eat!  Will it be blessing or curse?  People are not destroyed because God is punishing them, but because of a lack of knowledge.  God sent you the Holy Ghost so you could be led into all truth and be free!  The truth is that God created you healed, wants you healed, and is your Healer.  He will allow sickness if you choose it; He has no choice.  “Stand fast therefore in the liberty wherewith Christ hath made [you] free.”  “Resist the devil, and he will flee from you.”  “Neither give place to the devil” in your life.  Trample on serpents and scorpions and over all the power of the enemy!  You choose to be blessed!
