inheritance: property passing at the owner's death to the heir or those entitled to succeed.
When Jesus died, He made us his successors, those entitled to everything that He owns. And the things that He owns are far more important than those of this earth: joy, peace, life, eternity, happiness, contentment, friendship, love. The definition says "those entitled". The thing is, we aren't anywhere near entitled to anything that He could possibly give us. Day after day we turn against Him and hurt Him. I don't deserve anything that He could give me, but He gives willingly. Without His inheritance, I have nothing. It's amazing that He could look beyond my faults and transgressions and give me a full and eternal life.
