To quote Jesus Christ:
Matthew 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that cdoeth the will of my Father which is in heaven.
What does doing the will of "[Jesus'] Father" mean to you?
Also in Matthew chapter 7, Jesus says these are things you should do:
1 Judge not, that ye be not judged.
2 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
3 aAnd why beholdest thou the mote that is in thy brother’s eye, but considerest not the cbeam that is in thine own eye?
4 Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye?
5 Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye.
6 ¶ Give not that which is bholy unto the dogs, neither cast ye your cpearls before swine, lest they trample them under their feet, and turn again and rend you.
7 ¶ Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:
8 For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened.
9 Or what man is there of you, whom if his son ask bread, will he give him a stone?
10 Or if he ask a fish, will he give him a serpent?
11 If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?
Accepting Jesus as your personal savior.
