God bless you. When one is not properly fed, they are prone to diseases, weakness and are not able to perform well. They are malnourished. Now this is the natural, but we are spirit beings and our body is a shell. Therefore, we must feed ourselves with the word of God. For the word of God says "man cannot live by bread alone but by the Word of God. If we are not fed by the word of God, we become spiritually weak, down, depressed, hopeless, etc. This affects even our natural brain. One of the most famous prayers which Jesus taught is "Give us this day our daily bread." This feeds our soul. If we are not fed with spiritual food, we will not function in the spirit. For the word of God says "My word is spirit." Another spiritual food is obedience to God's will. John chp 4 speaks of this. Jesus says to His disciples "my food is to do the will of My Father.
Who are you in Christ? He calls us precious stones, He calls us branches and He is the vine. We are called the children of God. We are heirs of salvation. We are the redeemed washed in the blood of the lamb. We are called vessels, but God wants us to be vessels of honor. Our spirit man needs spiritual food. Even the fruits of the Spirit. Many Christians pray for many things but never seek the fruits of the Spirit. Gal 5:22 But the fruits of the Spirit are love, joy, peace, patience, kindness, goodness, faithfulness. For there is joy and peace in the Holy Spirit for outside of the Holy Spirit there is none. Deut 11:26 says Behold I set before you, blessing and a curse..Deut 30:15 See, I have set before you this day Life and Good, death and evil. The word of God also says "people perish for a lack of wisdom. Father I pray that this person will seek after You with all their heart and soul in Jesus Name. For You said in Your words "that they who seek You with all their hearts shall find You, and You shall make Yourself known unto them. God bless you again, and get into the word of God.
