'Obeys' in the Bible

I tell you the solemn truth, if anyone obeys my teaching, he will never see death."

Then the Judeans responded, "Now we know you're possessed by a demon! Both Abraham and the prophets died, and yet you say, 'If anyone obeys my teaching, he will never experience death.'

The person who has my commandments and obeys them is the one who loves me. The one who loves me will be loved by my Father, and I will love him and will reveal myself to him."
