These are the words that our Lord told apostle Paul in II Corinthians 12:9. Our Lord continued " for my strength is made perfect in weakness". For these words Paul said Therefore most gladly I will rather boast in my infirmities that the power of Christ may rest upon me.
Let us ask how can strength be made perfect in weakness ? In our and human life we observed we are a mixture of strengths and weaknesses. But what if various weaknesses are combined together ? This happened with our Lord Jesus Christ. In the day of his crucifixion, his disciples abandoned Him, God the Father and the Holy Spirit allowed Him to die on the cross for our salvation because He took in Himself sins of mankind . The forces of evil wanted to get rid of Jesus. In His humanity He laid down His divinity to give his life and blood. Add to that the cruelty, abuse, tremendous pain caused by lashes,carrying and the nailing on the cross and crown of thorn.
Our Lord endured all these " Grace and strength endured and triumphed because of Jesus' love for His Father, being led by the Spirit,and for the joy of seeing and fulfilling our salvation.
II Corinthians 13:4 explained For though He was crucified in weakness, yet He lives by the power of God. For we also are weak in Him but we shall live with Him by the power of God toward you.
II Corinthians 13:14 The grace of the Lord Jesus Christ, and the love of God and the communion of the Holy Spirit be with you all. Amen.
