3 John 1:2 Dear friend, I hope all is well with you and that you are as healthy in body as you are strong in spirit. NLT

Without the proper care the spiritual immune system will weaken, opening the door to the affects of the curse. 

Our spirits must be fed, strengthened, trained, developed and exercised in the same way as our bodies and our minds.  We can become so spiritually strong that our mountain moving faith will produce mighty results unhindered by any force whatsoever.

When John said we will prosper and be in health, he added, "Even as thy souls prospereth."  Man is a spirit, he has a soul consisting of a mind, will, and emotions and lives in a body and so there is spiritually prosperity, mental prosperity, physical prosperity.  To prosper spiritually we must be born again, accepting Jesus as Savior and making Him the Lord of our lives and then the spirit is reborn and brought into fellowship with God. This then puts us in the position to receive from Him all things that He has promised in His Word; but if our spirit is weak then we will not be able to receive those things.  The stronger the spirit the easier it is to receive, the easier to be able to take hold of what God has for us.

We feed and strengthen our inner spirit and it's spiritual immune system by putting the Word of God in our eyes and ears and from there going into our heart. Being strong in our spirit we will be able to tell our mouth what to say and not to say and that is crucial.  Out of the abundance of our strengthened heart we will speak faith words that produce what the Word says about us.   

Ephesians 6:10  Finally, my brethren, be strong in the Lord, and in the power of his might. KJV

Ephesians 6:10  In conclusion, be strong in the Lord [be empowered through your union with Him]; draw your strength from Him [that strength which His boundless might provides]. AMP

Joel 3:10 …let the weak say, I am strong. KJV

Joel 3:10 …let the weak say, I am strong [a warrior]!

Feeding the spirit every believer has the potential to walk in a greater place of supernatural strength on the inside.  The stronger our spirit, the easier it is to receive, the easier it is to resist the devil and sin, the easier it is to stand on the Word of God, and the easier it is to say right things.

If a person doesn't feed their body then they will die but a spirit not fed the Word of God will not cease to exist but it will just get weaker and weaker and weaker.

I want to pray for you believers, that you are strong in the Lord and in the power of His might and you are getting stronger every day and whatever trouble comes you are able to stand firm, stand strong because you are getting stronger in the Lord, stronger in the power of His might.  I pray you will train your spirit to be strong and resist sin and receive everything in Christ.  I pray your strong spirit will sustain you in bodily pain and trouble.  I thank the Lord for it all in Jesus' mighty Name.  Amen.
