The Lord is gracious and merciful, slow to anger and abounding in steadfast love. The Lord is good to all, and his compassion is over all that he has made. All your works shall give thanks to you, O Lord, and all your faithful shall bless you. They shall speak of the glory of your kingdom, and tell of your power, to make known to all people your mighty deeds, and the glorious splendor of your kingdom. Your kingdom is an everlasting kingdom, and your dominion endures throughout all generations. The Lord is faithful in all his words, and gracious in all his deeds. The Lord upholds all who are falling, and raises up all who are bowed down. (Psalm 145:8-14, NRSV)
The Lord is abounding in steadfast love.
What does that mean?
Love according to Merriam-Webster Online is (at least the definition that fits):
a: unselfish loyal and benevolent (see benevolent 1a) concern for the good of another: such as (1): the fatherly concern of God for humankind (2): brotherly concern for others b: a person’s adoration of God
And Steadfast according to Merriam-Webster Online is:
1a: firmly fixed in place: immovable b: not subject to change the steadfast doctrine of original sin — Ellen Glasgow
2: firm in belief, determination, or adherence: loyal her followers have remained teadfast
So steadfast love is unchanging devotion or immovable concern. And abounding is existing in or providing a great or plentiful quantity. So there is no end to the unchanging devotion of God, who is good to all and whose compassion covers all that has been made!
So know we do not have to be perfect, we just need to trust the promises God made and know that He will always catch us when we fall, to set us back up and dust us off and send us back out to share His love!
