Mark 16:15:
And He said to them, "Go into all the world and preach the gospel to every creature."
No, Christians do not have to "shed the idea" that they need to disregard this commandment of God's.
Add to your verses, the following:
"Therefore, my dear brothers, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain." (I Corinthians 15:58)*
And these:
"Your attitude should be the same as that of Jesus Christ:
"Who, being in very nature God, did not consider equality with God something to be grasped, but made himself nothing, taking the very nature of a servant, being made in human likeness. And being found in appearance as a man, he humbled himself and became obedient to death-even death on a cross! Therefore God exalted him to the highest place and gave him the name that is above every name, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father." (Philippians 2: 5~11)**
Just a humble reminder: not only will those of us who recognize Him for who He is, but the knees and tongues of everyone, including Nancy Pelosi and her brood, the ACLU, the NEA, Ahmadinejad and his followers etc., will conform to His will:....every knee will bow and every tongue will confess that Jesus Christ is Lord, to the glory of God the Father!!
It's as simple as that. So we can rest assured in His comfort and follow His direction:
"Therefore, my dear friends, as you have always obeyed-not only in my presence, but now much more in my absence-continue to work out your salvation with fear and trembling, for it is God who works in you to will and to act according to his good purpose." (Philippians 2:12, 13)***

Note that Christians were commanded to go into the world and teach the Gospel, not conquer and enslave the unbelievers. That's the difference between Islam and Christianity. Well, a difference. The real difference is that Islam is basicly a political ideology which uses religion to win and hold control of its adherents.
