Isaiah 40:28-31. Do you not know?
Have you not heard?
The Lord is the everlasting God,
the Creator of the ends of the earth.
He will not grow tired or weary,
and his understanding no one can fathom.
29 He gives strength to the weary
and increases the power of the weak.
30 Even youths grow tired and weary,
and young men stumble and fall;
31 but those who hope in the Lord
will renew their strength.
They will soar on wings like eagles;
they will run and not grow weary,
they will walk and not be faint.
Knowing that we cannot stand firm in this world on our own, God promised to give us power from above. He never intended for us to live the Christian life in our own strength. When we rely on ourselves, we inevitably grow weary, discouraged, and weak. But the strength God offers is not of this world—it is supernatural, unstoppable, and sufficient for every trial and every battle.
This power is the same mighty strength that raised Jesus Christ from the dead. It is the authority of the risen Lord that utterly destroyed the work of the devil and crushed the power of death. It is the unstoppable presence of the Holy Spirit, who appeared on Pentecost like a rushing wind and tongues of fire, shaking the room and consuming everything in His path (Acts 2:2–3). That same power has now been given to us.
God has promised you spiritual strength so that you may stand firm against the schemes of the devil in this present darkness (Ephesians 6:10–12). Though invisible to the human eye, Satan actively works through thoughts, culture, systems, and ideologies to blind and mislead the world. He creates an atmosphere of spiritual confusion, leading people into false identity and hopelessness.
The evidence is everywhere: people suffering from loneliness, emptiness, anxiety, and depression. Countless souls battle invisible wounds, chronic fear, and incurable illnesses. All the while, disasters—natural, moral, and spiritual—sweep across the world, leaving devastation behind.
The enemy’s greatest deception is to convince people that he doesn’t exist. He lures people into evil practices, idols, and spiritual bondage through demons and evil spirits. He offers counterfeit success, only to cause people to fall hard after they reach it. He never stops targeting God’s people—accusing, tempting, dividing, and oppressing.
But this is why God gave the first promise of the gospel in Genesis 3:15: that the offspring of the woman would crush the head of the serpent. Jesus came as the Christ—not merely to comfort or inspire, but to conquer. He overcame the forces of darkness and freed us from Satan’s grip. And now, through faith in Him, we have been given authority over all the power of the enemy (Luke 10:19). Victory is no longer uncertain—it is guaranteed.
When you are filled with this spiritual strength, you will rise above your human limitations. Jesus said, “Very truly I tell you, whoever believes in me will do the works I have been doing, and they will do even greater things than these” (John 14:12). The Holy Spirit will heal what is lacking in you—your fears, your hesitation, your weaknesses, and your spiritual sluggishness. He will make you bold and fruitful.
Not only that, you will overcome the world. “Everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith. Who is it that overcomes the world? Only the one who believes that Jesus is the Son of God” (1 John 5:4–5). You are not fighting for victory—you are standing in victory.
Cultivate this spiritual strength until you are no longer intimidated by the world. Let the power of God so fill your life that you are not shaken by adversity or distracted by comparison. Grow in the authority of Christ until you no longer compromise with the values and voices of the world.
Rely completely on the Holy Spirit until you become the witness Jesus promised in Acts 1:8—His representative to the ends of the earth. As you walk in His power, God will lift you up on wings like eagles. You will run and not grow weary. You will walk and not faint (Isaiah 40:31).
Prayer. Father, I thank You for the spiritual strength You have given me in Christ. When I grow weary, give me Your power. When I am weak, increase my strength. Teach me to hope in You alone. Renew my strength so I will not tire, stumble, or fall. Make me soar by Your Spirit and stand as a true witness of Christ in all the earth. In Jesus’ mighty name, Amen.
