— Psalm 51:6, 10

The word heart comes from the Hebrew word lev, which carries the simple meaning of center, as in the will or intention of a person. 

My intention is to love the Lord, but the state of my heart (selfishness, negative thoughts, doubt, fear) tends to inhibit me.  To cleanse my heart of all impurities (not of God), I must start by admitting my weaknesses, asking the Lord for forgiveness and forgiving myself.  Spending time with the Lord—in his Word and in prayer, reconciles me to God and enables me to love him with all of my heart in the same way that he loves me, unconditionally.

All of Your Soul
 
Honor the Lord and serve him wholeheartedly.  Put away forever the idols … Serve the Lord alone … Choose today whom you will serve … As for me and my family, we will serve the Lord. 

—Joshua 24:14-15

Soul in Hebrew (nephesh) can be defined in many ways to mean heart, life, soul, wish or desire.  Some scholars have translated it to mean passion.

Passion today is often used to describe a desire to achieve wealth, fame, fortune or notoriety, but rarely as a way of how to love the Lord.  As a result, I find it difficult to do on a daily basis.  I am faced with many distractions.  The imagery of big homes, big cars, and big screens cause me to have big desires.  Most of these desires interfere with me wholeheartedly serving and being passionately in love with the Lord.

No one can serve two masters.  For you will hate one and love the other, or be devoted to one and despise the other.

— Luke 16:13

To truly love the Lord with all of my soul (and passion), I must reevaluate my priorities and not create or serve any other god before the Lord; not money, not fame, not power, not love (of any thing or anybody).

All of Your Mind

Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is—his good, pleasing and perfect will.

— Romans 12:2
 
The Hebrew word dianoia translates to the word mind, meaning to think through and think over in meditation and reflection.

I have prayed often that I would know God’s will for my life.  Looking back at many of these moments, I can see how I didn’t hear His will because my mind was not on Him, but rather on things of the world (my job, my finances, my wants, my desires).  I was so engrossed in being like the world, that I lost focus of the things of God (spending time in prayer, growing in his Word and serving others).  What I was honestly looking for was confirmation of my will, not his.

In order to love the Lord with all of my mind, I need to be one with the mind of Christ.  That takes time, patience, and perseverance, as it would with any relationship.
