How can one embrace Islam and pronounce the Two Testimonies of Faith (Shahadatain)?

The advice of some people to be slow and deliberate in entering Islam is strange, for death may come at any time. One should hasten to enter Islam immediately, so that the Muslim may meet his Lord upon the religion which He accepts no other. You have read enough about Islam and the Qur’an, so hasten and do not deprive yourself of the reward.
