In Ezekiel’s vision it was a literal mark, but it is not such a thing today. What, then, is the mark, and how is it inscribed as it were on the foreheads of people?

3. What is that mark today, and what does putting it figuratively on the forehead indicate?

³ Since the marked ones back there were the loyal pure worshipers of Jehovah, you must ask yourself, ‘Am I a true, loyal worshiper of Jehovah?’ Then you can look for the identifying mark. Yes, the symbolic mark today is that which marks or identifies you as a worshiper of the Sovereign Lord Jehovah. Figuratively it is put upon your forehead, not to picture that you have had Bible knowledge concerning Jehovah God put into your head and inscribed upon your brain.

4. So what more than mere head knowledge is required, and since when and by whom has the marking work been going on?

⁴ So more is required than mere knowledge in your head. It is not what you have in your head that counts, but what you really are as a personality. As if stamped in your very forehead, it becomes plainly visible and readable to all who look at you and study you. This personality, which does have Bible knowledge as a basis, has to be developed in you.

The anointed remnant helped these persons loyal to Jehovah to grow in knowledge and understanding to the point where they made their personal decision and dedicated themselves to Jehovah God through Jesus Christ his Son and symbolized this dedication by being immersed in water. By thus becoming “disciples” of Jehovah’s Son, Jesus Christ, they got marked in their foreheads.​—Matt. 28:19, 20.

Is not the Christlike personality that they thus put on an approved mark that openly distinguishes them as if they were plainly marked in their foreheads? Yes, indeed!
