Our flesh and the Holy Spirit are antagonistic. Galatians 5:17 says, “For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another…”
That is a perfect description for why we struggle. We don’t want to let go of our flesh.
Psalm 34:9-10 says, “Oh, fear the Lord, you His saints! There is no want to those who fear Him. The young lions lack and suffer hunger; but those who seek the Lord shall not lack any good thing.”
The fear of the Lord, seeking Him, and patiently enduring our trials are three areas that supply anything we lack. Psalm 84:11 says, “For the Lord God is a sun and shield; the Lord will give grace and glory; no good thing will He withhold for those who walk uprightly.”
Endurance means to bear up under difficult circumstances with hopeful fortitude that actively resists weariness and defeat.
