In a very important sense, we are all converts. Every Muslim man and woman worth our salt.
That means we have all given our Islam some serious thought. And we have all -- should I say "thereafter"? -- then made a serious commitment to Allah.
Without such a serious stage of analysis and reflection, and personal decision-making, there is really no Islam. Even though God Almighty's door is open to all.
And even though God Almighty never turns away anyone from his doorstep empty handed.
