Step-by-step explanation:
The irony that Sojourner Truth points out in these lines is that men often use religious arguments to justify the subordination of women, despite the fact that women played a crucial role in the creation and upbringing of the central figure of Christianity, Jesus Christ.
By invoking the figure of Christ and his relationship to women, Truth is highlighting the hypocrisy of the argument that women are somehow inferior to men. She argues that if women played such a vital role in the birth and upbringing of Christ, then how can they be considered less deserving of rights and respect than men?
Furthermore, Truth's assertion that women should be allowed to turn the world "right side up again" is a call to action, suggesting that women have the power to effect positive change in society if only they are given the opportunity to do so. The fact that this call to action is directed at men further underscores the irony of their attempts to limit women's rights and opportunities based on religious or other flawed arguments.
