Psalm 103 & Isaiah 40 Isaiah must have been a bird watcher. He listed some spiritual principles and spiritual lessons to learn from the eagle: “those who wait for the LORD will gain new strength; they will mount up with wings like eagles, they will run and not get tired, they will walk and not become weary.” [Is 40]
The eagle pictures the biblical marriage vows, committing to living together “until death do us part.” “For this reason, a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh.” [Gen 2] Then together they build their “home” at the top of trees or cliffs where they securely can raise their young.
Like the eagle, believers are to be “spiritually vigorous until death.” [Constable] Eagles remain vigorous, symbolizing power, freedom, and transcendence exceeding in superiority to the end of their lives, which can be up to thirty-eight years. They have been blessed with a superior vision to see their prey up to three miles away. So too, believers have the indwelling Holy Spirit who anoints us with a spiritual vision to spot false doctrines and teachers.
Just as the eagle never surrenders to its prey but fights them to the end, we too should fight the spiritual forces of this darkness dressed in our spiritual armor and never surrender to them. [Eph 6]
Joshua told the Israelites to “choose you this day whom you will serve.” [Joshua 24:15] And that same choice is given to us.
