To believe with your heart means to believe God apart from your body!
We have to learn how to contact God with our spirit because we cannot contact Him with our mind or emotions.
The Word of God is the key to connecting with God.
1 Corinthians 2:14
The natural man (mind) does not receive (or have the ability to understand) the things of the Spirit of God, they are foolishness to him. These things are spiritually understood and discerned.
To believe with the heart is to believe with the spirit. How does our spirit get faith that that our intellect cannot get? The Word of God.
Man should not live by bread alone but by the Word of God which is spiritual food. The Word is spirit and faith food!
The physical man believes by its senses and feelings. It believes what it sees, feels or thinks.
Believing with your heart/spirit:
Having confidence in the Word even though emotions, feelings and circumstances determine otherwise.
Example: you feel guilty for something you did. The Bible calls you righteous because you are saved but how can you believe you are righteous when your body and past has so much contact with unrighteousness? Believe with your heart
Evicted: Situation looks like you are going to get evicted but God says He will provide for all your needs. Believe with your heart
Cancer: doctor says you have cancer but God says by His stripes you are healed
Broke: bank account is telling you that you have insufficiency and lack, God says that we will have the abundant life.
Believe with your heart, not based on your natural understanding.
When you don't believe with your heart, you cannot contact God so all the provisions He has for you can't be released!
Dont deny your spirit!
Proverbs 3:5~7.Trust in the Lord with your heart/spirit, not your understanding
The result: peace!
Hebrews 4:3: the person who believes enters into rest. How can you rest when you are worried
Philippians 4:7 God will give the peace that passes all understanding
Isaiah 26:3 God will keep me in perfect peace if my mind is stayed on Him.
