Do/did you Love your parents with all your heart/devotion? Do/did you love your spouse with all your heart/devotion? Do you love your children/ grandchildren with all your heart /devotion?<
If you have answered yes to any of the following then using your own logic it is impossible for you to Love God with all your heart/ devotion.
