In the custom of the times, the names of Bible people often had a special significance or meaning. In some cases God renamed people for this reason (eg. Abram, meaning ‘exalted one’ was changed by God to Abraham, ‘father of many’, and Sari, his wife was changed to Sarah meaning 'princess' – Gen 17:5,15).
If our name is in the Book of Life this guarantees we will be in heaven, but if our name is not recorded there we will not be able to enter (Lk 10:20; Phil 4:3; Rev 3:5, 20:15, 21:27).
Having a ‘good name’ means we can be depended on to honour our word, consistently doing what is legally and morally right whatever the cost. After all, ‘Christian’ means Christ’s one. How do I rate?
