The resurrection validated Jesus as the Son of God. The resurrection also guaranteed our salvation. However, there is SO MUCH MORE to it than those two important aspects.
John 5:28-29 Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, and shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
This passage, of course, speaks directly to the future judgment of all people. There will indeed be a resurrection at the end of the age. This Bible doctrine is plain enough for everyone to understand. The fact that I will be resurrected into one realm or the other should be motivation enough to learn what it means to live a good life.
However, many are trusting in only their good works. Let us remember that without a living relationship with the Living One, our good works are meaningless:
Isa.64:6a But we are all as an unclean thing, and all our righteousnesses are as filthy rags;..KJV
Mt 7:22-23 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity. KJV
A life of doing good works, of being a good person, means absolutely nothing if those works are not born from the Spirit. They cannot be born of the Spirit if you are not born again.
Jn 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. KJV
