How many times in the New Testament does the word success appear in Scripture?

Answer 1

For an English term, it usually depends upon the version in use. See the only incident of the term 'success' in the KJV or Authorized Version of The Bible:

Joshua 1:8

This book of the law shall not depart out of thy mouth; but thou shalt meditate therein day and night, that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous, and then thou shalt have good success.
