Life = Jesus Christ

"I am the way, the truth, and the life. No one comes to the Father except through me" (John 14:6). 
"In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him and without Him nothing was made that was made. In Him was life, and the life was the light of men. And the light shines in the darkness, and the darkness did not comprehend it" (John 1:1-5).

Sin = Death

"For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord" (Romans 6:23).

So the ultimate meaning of life is to glorify God in everything you do and when you do this, you will experience the true meaning of your life "For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them" (Eph 2:10).
