How do we love God?
Simple. In Matthew 22: 37-38 he sums it up in the following way:

Jesus answered:

• "You shall love the Lord your God with all your heart, with all your soul and with all your mind". This is the first and most important commandment.

We love God when we love him with all our heart, with all our soul and with all our mind. Easy, right?

Not necessarily.

Do we know what our heart is? How can I love God with my heart? How is your soul? What is it? How do you love God with my soul? With my mind?

Many times we read this verse and we summarize it: "we must love God with all that we are" and that's it. But Jesus makes a distinction between every aspect of who we are. The fact that Jesus has put the word "and" means that it has to be with all these aspects at once - I can not love God with my heart, but not my soul.
