The only question that each of us really need to ask and that really has eternal ramifications is:
WHO IS JESUS TO ME?
If we answer that Jesus is a Great Teacher, Leader or Prophet that He can do nothing more in our lives then provide us teachings and principles which in most cases we cannot sustain or completely live up to.
But if we answer that Jesus is the Son of God, then we have full assurance and hope that He can and will save us and grant us eternal life that starts now when we put our full trust in Him.
To God eternal life is knowing and believing in His Son, Jesus Christ as Lord and Saviour.
John 17:3 Now this is eternal life: that they may know you, the only true God, and Jesus Christ, whom you have sent.
