Rejoice, celebrate, and give thanks for all your flaws, mistakes, and failures. God uses our mistakes, flaws, and weaknesses like a gardener pruning a vine. He prunes us, believers who are branches in the vine, who is our Lord and Savior, so that we can bear good fruit. The pruning process will be painful, just as discipline is painful when it is administered, but later it will yield a harvest of righteousness for God's eternal kingdom (Hebrews 12:11).
So, celebrate your weaknesses as Paul did, because in our weakness, God's power is made more manifest (2 Corinthians 12:9-10). We should not be discouraged or lose hope when we are reminded of our limitations and flaws, or when we fail. Thomas Edison made more than a thousand mistakes before he finally found a solution to creating the lightbulb. We should be solution-focused, not problem-focused.
It is in our weakest moments that God's mighty and unlimited power is revealed. The same power that raised Christ, our Lord, and set Him at God's right hand, giving Him all authority and power to judge at His second coming, is within us (Ephesians 1:19-21). The power in us is greater than he who is in the world (1 John 4:4).
So, celebrate and rejoice that when you are weak, you are strong in the mighty power of our Heavenly Father, Creator of heaven and earth. Do not be discouraged, for it is not by might, nor by power, but by the Spirit of the Lord that works powerfully in you to will and to act according to His will and purpose (Zechariah 4:6, Philippians 2:13). He will help and strengthen you at all times.
As it is written: "Do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with My righteous right hand" (Isaiah 41:10).
