Loving God with all our heart is the most important commandment. But what does it mean? Unfortunately we live in a time where the word love has ended meaning only a feeling. Loving someone is confused with "I like him". However, that someone "likes me" does not necessarily constitute love in biblical terms. Because in biblical terms love is closely connected with doing and specifically loving God with doing what God wants, that is, His commandments, His will. Jesus made this very clear when he said:

John 14:15
"If you love me, keep my commandments."
