“Hear, O Israel! The LORD is our God, the LORD is one! You shall love the LORD your God with all your heart and with all your soul and with all your might. These words, which I am commanding you today, shall be on your heart. You shall teach them diligently to your sons and shall talk of them when you sit in your house and when you walk by the way and when you lie down and when you rise up. You shall bind them as a sign on your hand and they shall be as frontals on your forehead. You shall write them on the doorposts of your house and on your gates." (Deuteronomy 6:4-9)
The way to truly know the heart of God is to constantly have His words at the forefront of your attention. We don't have to strap them to our heads like the Jewish leaders did. But we do need to hide them in our hearts, constantly meditate on them.
And it's not a bad idea to create habits in your day that remind you to meditate on them - times to talk about the scriptures, times to read them and memorize them, posting scriptures on your bathroom mirror and on the refrigerator door, configuring your Outlook program to pop up scripture reminders, following Twitter accounts that provide daily scriptures (I like @proverbsfeed).
