“Let the weak say, I am strong” (Joel 3:10; ASV). That is a powerful faith confession. All through the Bible we are reminded that God is our strength, for example, “He gives power to the weak and strength to the powerless” (Isa 40:29; NLT) and “But those who
trust in the Lord will find new strength. They will soar high on wings like eagles. They will run and not grow weary. They will walk and not faint” (isa 40:31; NLT). What an amazing promise!
In the New Testament Paul prays for the Colossians that they “would be energized with all His explosive power” (Col 1:11; TPT). The Greek word for energized is related to the word “dunamis” which is where we get our word dynamite from! Paul also prays for the Ephesians to be “strengthened with might through His Spirit in the inner man” (Eph 3:16; NKJV). This is referring to an inner strength. God can strengthen us both spiritually and physically. (See also Eph 6:10.)
It is God who gives us the strength to live our lives and do what He has called us to do (Phil 4:13). We observe that strength in the life of Jesus and also Paul and the apostles, whether they were teaching and preaching, ministering to those in need or enduring persecution.
Look to God as you go through your day, if you are feeling weak and tired confess any of the strength scriptures over your body and believe you receive by faith.
