From Conception - At conception you are Infinite Spirit and Soul which are invisible, eternal, unending, forever, life without end but contained in your visible mortal body which is finite, non eternal and has end. So that when the body which is the jacket dies, the spirit and soul continue to live on in an immortal body in the eternal life. Where we now are to live will depend on God's judgement with regards our life's decisions and choice we made.
Scripture: "May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ.1 Thessalonians 5:23
