The arguments in this half of the chapter are explanation not motivation. It explains what kind of body we'll have. it explains the relation of the resurrection to the law and to sin. It will not be more-of-the-same only longer, when we are resurrected. Part of the hope is that things will be different.
Found myself longing for the resurrection. . . sown in weakness, raised in power. Yes!
Friends who do not share the perspective of the resurrection, the accountability and hope, will corrupt good morals. Be sure of it. (1 Cor. 15:33). Morality ultimately depends on the resurrection.
The conclusion is not to let circumstances dictate how you spend your life. Work for the Lord. The resurrection means that your labor is not in vain (1 Cor. 15:28)
