By putting our faith in Jesus Christ’s sacrificial death on our behalf, by letting Him bear the guilt of our sin, and by receiving, by faith, His righteousness, which is imputed to us, we are justified. In that righteousness, I can face God, death, and eternity without a tremor, without fear.
The apostle John wrote in his first epistle,
And the witness is this, that God has given us eternal life, and this life is in His Son. He who has the Son has the life; he who does not have the Son of God does not have the life. These things I have written to you who believe in the name of the Son of God, in order that you may know that you have eternal life. (1 John 5:11–13 nasb)
God has given a testimony to the whole human race that He has offered to us eternal life. This life is in the person of His Son, Jesus Christ. If we receive Jesus Christ, in Him we have received eternal life.
Notice, this is stated in the present tense: “He who has the Son has the life.” It is not something that is going to happen after death. It is something that happens now, in this time-space world. If you wait until after death to accept His life, you will have waited too long; it will be too late. Settle that issue now! He who has the Son has life. Make sure that you, too, have life!
