And this is the testimony, that God gave us eternal life, and this life is in his Son.
English Standard Version (ESV)
It's easy to read this and think "eternal life is a future reward." But John emphasizes it's presently "in his Son," meaning the life God gives isn't just something that starts after we die, but a reality we can experience right now through Jesus.
And this is the testimony, that God gave us eternal life, and this life is in his Son.
English Standard Version (ESV)
John is building a case, contrasting the truth of God with the lies of false teachers who deny Jesus is the Son of God. He's already declared that anyone who believes in Jesus has eternal life, and here he explains why that's the definitive truth: God Himself is the witness, offering this life solely through His Son. This sets up the following verses where he emphasizes the importance of believing in God's Son to truly possess this life.
We often think of eternal life as something we earn or achieve. But what if it's purely a gift from God? This verse points to its origin.
John is clear: God gave us eternal life. This isn't a reward for good behavior or a prize for faithful service. It's a free, undeserved gift. The Greek word for 'gave' suggests a generous, ongoing bestowal. This gift wasn't promised for some distant future; it's something we can have now because of God's initiative.
Where does this incredible gift of eternal life reside? It's not in a place or a feeling, but in a Person. This concept unpacks who holds this life.
The verse states unequivocally, 'and this life is in his Son.' Jesus isn't just the way to eternal life; He is eternal life. All that God offers in terms of unending life is found exclusively in and through His Son, Jesus Christ. To have eternal life means to be united with Him, to be in relationship with Him. It’s a life that originates from God, is given by God, and is possessed in God's Son.
