What does it matter?
Well, for one, you now know you won't actually die. Others may look upon your physical body as having died, but you will be fully conscious, feel well, calm, young (your Spirit body does not age past maturity) and you will have the wonderful opportunity of meeting the Lord Jesus. Does that part concern you? Jesus died in atonement for your sins ("Redemption"). Your sins will not keep you from eternal life in God's kingdom. They will not keep you from seeing your loved ones again. What will?
Jesus wants your love in return for His amazing love for You. You cannot love someone who you do not believe exists. You cannot love someone who you do not know and trust. You must know, love and trust Jesus with your eternal life. You must believe in Jesus. Okay, what else?
Jesus gave us a new commandment while He was here on earth. Love one another. "As I have loved you, so you also should love one another." John 13:34 Love those around you as you love yourself. Share what you have with others. Feed the hungry, give drink to the thirsty, take in the stranger, cloth the naked, take care of the sick and visit the imprisoned as each opportunity presents itself. Matthew 25:31-46 Then, look forward to an eternal life in His kingdom ("Salvation"). It's all about love, as many of the scientists mentioned above will tell you.
