If our only requirement to make it into heaven was to be "good", Jesus would've never had to come here and die. It doesn't matter how "good" we are, if we aren't obedient to God's word and do as He says, our "goodness" is null and void. Many people will try to justify their "goodness" on the day of judgment, but only those who have been obedient to God's word, will make it in.

Matthew 7:21-23

v.21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven: but he that doeth the will of my Father which is in heaven.

v.22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in they name have cast out devils? and in thy name done many wonderful works?

v.23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
