Was apostle paul childlessness as a result of his killing as a sinner?

Answer 1

Paul was childless because he didn't marry. The commission God gave him put him in constant peril. He was beaten, stoned, shipwrecked, starved, threatened... you name it. And that was just against himself. He probably wouldn't have been able to do all that and still accomplish God's Work with threats to a wife and family constantly on the table.

Besides the last part of Paul's life he spent as a willing prisoner in Rome [Acts 28]; the rough and tumble life Paul lived, constantly on the go and in mortal danger, was not conducive to marriage:

"Three times I was beaten with rods. Once I was stoned. Three times I was shipwrecked. Once I spent a whole night and a day adrift at sea. I have traveled many weary miles. I have faced danger from flooded rivers and from robbers. I have faced danger from my own people, the Jews, as well as from the Gentiles. I have faced danger in the cities, in the deserts, and on the stormy seas. And I have faced danger from men who claim to be Christians but are not. I have lived with weariness and pain and sleepless nights. Often I have been hungry and thirsty and have gone without food. Often I have shivered with cold, without enough clothing to keep me warm. Then, besides all this, I have the DAILY BURDEN of how the churches are getting along." (II Cor.11:25-28 NLT New Living Translation)

"...This is only MY SUGGESTION. It is not meant to be absolutely true. I WISH EVERYONE COULD GET ALONG WITHOUT MARRYING, JUST AS I DO. But we are not all the same. God gives some the gift of marriage, and to others He gives the gift of singleness." (I Cor. 7:6-7 NLT)

"...the LORD in His Kindness has given me Wisdom that can be trusted, and I will share it with you. BECAUSE OF THE PRESENT CRISIS, I think IT IS BEST TO REMAIN JUST AS YOU ARE. If you have a wife, DO NOT END THE MARRIAGE. If you do not have a wife, DO NOT GET MARRIED. But if you get married, IT IS NOT A SIN... However, I am TRYING TO SPARE YOU THE EXTRA PROBLEMS THAT COME WITH MARRIAGE. (verses 25-28)

"Now let me say this, dear brothers and sisters: THE TIME THAT REMAINS IS VERY SHORT, so husbands SHOULD NOT LET THEIR MARRIAGE BE THEIR MAJOR CONCERN. Happiness or sadness or wealth should not keep anyone from DOING GOD'S WORK... In everything you do, I want you to be free FROM THE CONCERNS OF LIFE. An unmarried man can spend his time doing the LORD's Work and think how to please Him. But a married man can't do that so well. He has to think about his earthly responsibilities and how to please his wife. His interests are divided... I'm saying this for your benefit, not to place restrictions on you. I want you to do whatever will help you SERVE THE LORD BEST, with as few distractions as possible." (verses 29-35).
