When we receive Christ, the Holy Spirit indwells us, thus purifying us and making us eternal.

"I am the resurrection and the life; he who believes in Me will live even if he dies, and everyone who lives and believes in Me will never die. Do you believe this?" John 11:25-26

In Greek, bios in the Bible often refers to structural life, existence in space and time. It is temporary. Zoe frequently expresses the God-quality of life, eternal and pure. Bios is finite—limited. Zoe is infinite—unbounded by space and time. Our bios structures are intended as the temple of God, for His indwelling Zoe, through His Spirit. Prior to receiving Christ, the temple is empty. When we receive Christ, the Holy Spirit indwells us, making us alive with His Zoe. Yet our bodies are still bios structures, and will decline and die. Someday we will have a new body, perfectly aligned with the Zoe that is our very life.
