Jesus reminds us that God requires our entire heart, our whole life, and complete submission to His will. This is the first and greatest commandment of all. It’s the foundation of our relationship with God. We tend to forget about this when we disconnect from God and no longer put Him in the center of our life. While we have a certain amount of love for God, He is not always the object of all of our affection. So how do we carry out the Lord's instruction to love Him with all of our heart, our soul, and our mind?
The word "heart" in the scriptures refers to who you truly are on the inside. Your identity, your inner self, your desires, your values, and your principles reflect the true state of your heart. All our actions are done with intention, and are done from the heart. We can hide nothing from God. The contents of our hearts are on full display. Only when we turn to the Lord with our hearts will our love for Him deepen. His thoughts, feelings, and decisions become our thoughts, feelings, and decisions as He infuses Himself into us. 
God also asks us to devote our souls - our lives to His service. When we think of God at all times, we see God in all things. Therefore, it is so crucial to attend church, engage in Christian community, and study the Word regularly. We frequently need to recalibrate and recenter our hearts and minds to God’s will so we will never live apart from God.

Dear Heavenly Father, You are my true desire, and pleasing You is my priority. I have been distracted and preoccupied with things lesser than you. Lord, I ask that You steal my heart back and keep me close to You. Help me to always put You as the center of my heart, my life, and my mind, and glorify You in everything I do. 
In Jesus's name I pray. Amen.
