If all our love goes to God, then it cannot be divided. Does this mean that we should never love anyone else? What about loving one’s own husband or wife or children? What about loving other people? Jesus went on immediately to say that the second most important command is this:
Love your neighbor as yourself (Mark 12:31, quoting Leviticus 19:18).
The Christian husband should love his wife (Ephesians 5:25). Neither Moses nor Jesus thought that these kinds of love took love away from God.
Why? Because it is God’s will that we so love others. The true way to show love for God is to obey God.
For this is the love of God, that we keep his commandments (1 John 5:3).
If God is truly “LORD” He deserves our full obedience. We cannot claim to love Him while forgetting who He is and what He deserves. Real love treats Him as the real God He is. So, when we love others, as He commanded, that fits perfectly into true love and devotion to Him.
