Matthew 22:27-29
We are to love God with everything we are and this is the FIRST commandment. I think this equips us with a couple of things we really need before we pour into others.
One - as we lean into loving Him we are gently reminded of our own shortcomings, our own areas of weakness, our own tendency toward pride and self-centeredness. This helps us to love others with gentleness and patience.
Two - as we lean into loving Him we are filled up. He leads us beside still waters. He makes us lie down in green pastures. He restores our souls. He pours into us the rest and peace we need so we can overflow onto others joyfully.
Love Him well, then love them well.
