Moses was a murderer and had a speech impediment. David was a murderer and adulterer. Isaiah was a man of unclean lips. The word Jacob means trickster. He lied to his own father stealing his brother’s birthright. Yet in the end, God changed his name to Israel and named his family after him. Peter denied Christ. Paul persecuted Christians.
And yet God still worked through these men for his purposes and glory. Through God's power, their points of weakness became their greatest strengths. God uses people in spite of their shortcoming; he uses imperfect vessels to deliver and complete a perfect work, that we may know that this is not of men but could only be God's doing.
Brothers, think of what you were when you were called. Not many of you were wise by human standards; not many were influential; not many were of noble birth. But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong. He chose the lowly things of this world and the despised things—and the things that are not—to nullify the things that are, so that no one may boast before him. It is because of him that you are in Christ Jesus, who has become for us wisdom from God—that is, our righteousness, holiness and redemption. Therefore, as it is written: "Let him who boasts boast in the Lord." - 1 Corinthians 1:26-31
“Moses was a murderer and had a speech impediment. David was a murderer and adulterer. Isaiah was a man of unclean lips. The word Jacob means trickster. He lied to his own father stealing his brother’s birthright. Yet in the end, God changed his name to Israel and named his family after him. Peter denied Christ. Paul persecuted Christians.”
And don’t forget that evil men spread lies about prophets of God, even about the Savior, throwing false accusations and lying witnesses against them to lead others away from accepting them.
