This two part word is derived from Latin. Ab meaning from and unda meaning wave or surge.
If you’ve ever watched the ocean as the tides were rising you get an excellent grip on it’s meaning. As the tides roll in each wave hits and begins it’s recession only to be overcome by the next wave before it is gone. The combined effect continues to grow until the beach begins to shrink and each successive wave builds upon the last to cover the once dry land with the vibrant life of the ocean.
The combination abundo serves as a wonderfully descriptive picture of the grace of God.
Numbers 14:18 tells us that “The LORD is slow to anger and abundant in lovingkindness,…” In Psalm 5:7 David writes “… by Your abundant lovingkindness I will enter Your house, …” And again in Psalm 86:5 he cries “For You, Lord, are good, and ready to forgive, And abundant in lovingkindness to all who call upon You.”
Time after time in the Psalms, in the prophets and also in the new testament the lovingkindness of God is referred to as abundant. The Gracious favor of the Lord comes upon us in rapidly successive waves each one increasing the power of the last until we are greatly overwhelmed by it’s splendor.
Perhaps the greatest description of this abundance is found in Ephesians 1:7-8a. “In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace which He lavished on us. … ”
All of the riches of God’s grace have been lavished upon us. God has not given us only a little grace, nor has he given us only enough grace. Rather God has poured upon us grace upon grace upon grace. The dynamic powerful waves of God’s grace continually pour over us overwhelming all of our sin and completely washing away our abilities to resist him. Our God has given us grace and it is an abundant grace!
