Acts 2:36-37 (KJV)
Even though the men listening to Peter's sermon probably weren't the ones who arrested Jesus, spit on him, put the crown of thorns on his head, or drove the nails into his hands, Peter told them "...ye have crucified, both Lord and Christ." But some of those men may have been the ones who said, "crucify him!" or maybe they were just indifferent to the unjust killing of a righteous man. These men then rightfully repented of this sin.
Its time for Americans to do the same. We have murdered unborn babies and (as you can see from the above video) killed innocent children with our bombings in Iraq, Afghanistan, Pakistan, and other places. If we turn away from this and all of other sins, and ask God's forgiveness he will heal our land. But failure to acknowledge this sinfulness will result in our downfall. Most conservatives can recognize that there is hypocrisy, corruption, theft, and murder (of unborn babies) going on in the government. But for for some reason they believe that our military is incapable of this and that it is distasteful, dishonorable, unpatriotic, and ingratitude to suggest otherwise. The above video is proof to the contrary. Our military strength is a gift from God and does serve a legitimate purpose, but we must stop idolizing it. We must repent.
