The Lord promises again and again in His Word that He will strengthen us. He knows that, as human beings, we often feel our weakness to the point where we don’t believe we CAN be strong.
In Joel 3:10 we read, “Let the weak say, I am strong.” Notice that strength is first something we confess with our mouths. We SAY to ourselves, “I am strong.” Note, too, that the Bible doesn’t say we were strong or that we will be strong. It says we are to speak to ourselves in the NOW of our circumstances and say, “I AM strong!” What a good word that is to us when we are feeling weak…unable to cope or to bear up under the pressure, to be patient or have courage. In that very moment…in that very circumstance…we can claim, by our faith, the provision of God to us: “I AM STRONG!”
On what is our strength based? Our strength is not in ourselves but in Christ Jesus who lives within us by the power of the Holy Spirit. In Isaiah 40:28–29, the prophet said, “Hast thou not known? Hast thou not heard, that the everlasting God, the Lord, the Creator of the ends of the earth, fainteth not, neither is weary? There is no searching of his understanding. He giveth power to the faint; and to them that have no might he increaseth strength.” Our strength does not come from our own abilities or power, but from the wisdom and power of God, which is poured into us on a daily basis any time we admit our weakness and ask Him to replace our weakness with His strength.
The apostle Paul wrote, “Be strong in the Lord and in the power of his might” (Ephesians 6:10). Take that as God’s word to you today! You can be strong in any situation or circumstance you face today because the Spirit of God is strong within you!
