1 John 5:11-13

And this is the testimony: that God has given us eternal life, and this life is in His Son.
He who has the Son has life; he who does not have the Son of God does not have life.
These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God.

Romans 5:5-8

Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us.
For when we were still without strength, in due time Christ died for the ungodly.
For scarcely for a righteous man will one die; yet perhaps for a good man someone would even dare to die.
But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us.

Matthew 18:1-5

At that time the disciples came to Jesus, saying, “Who then is greatest in the kingdom of heaven?”
Then Jesus called a little child to Him, set him in the midst of them,
and said, “Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven.
Therefore whoever humbles himself as this little child is the greatest in the kingdom of heaven.
Whoever receives one little child like this in My name receives Me.”

John 17:1-3

Jesus spoke these words, lifted up His eyes to heaven, and said: “Father, the hour has come. Glorify Your Son, that Your Son also may glorify You,
as You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him.
And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.”
