“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.”
I John 5:13 NKJV
The absolute certainty and assurance that you have eternal life comes from the absolute certainty and assurance that the Word of God is absolutely true, nothing but true, and forever true.
So when He says:
John 3:15 that whoever believes in Him should not perish but have eternal life.
You can have
absolute certainty that: "whoever believes in Him should not perish but have eternal life." Because His Word is
absolutely true, nothing but true, always and forever.
Let us "believe on Him" then. And this is the first thing many people dont want to know:
James 2:20 But do you want to know, O foolish man,
that faith without works is dead?
What works?
I John 3:23 And
this is His commandment: that we should
believe on the name of His Son Jesus Christ and
love one another, as He gave us commandment.
Luke 6:27 But I say to you who hear:
Love your enemies, do good to those who hate you,
28 bless those who curse you, and pray for those who spitefully use you.
29 To him who strikes you on the
one cheek, offer the other also. And from him who takes away your cloak, do not withhold
your tunic either.
30 Give to everyone who asks of you. And from him who takes away your goods do not ask
them back.
31 And just as you want men to do to you, you also do to them likewise.
35 But
love your enemies, do good, and lend, hoping for nothing in return; and your reward will be great, and you will be sons of the Most High. For He is kind to the unthankful and evil.
36 Therefore be merciful, just as your Father also is merciful.
37 Judge not, and you shall not be judged. Condemn not, and you shall not be condemned.
Forgive, and you will be forgiven.
38 Give, and it will be given to you: good measure, pressed down, shaken together, and running over will be put into your bosom. For with the same measure that you use, it will be measured back to you.”
Matthew 7:12 Therefore, whatever you want men to do to you, do also to them, for
this is the Law and the Prophets.
I John 4:18
There is no fear in love; but perfect love casts out fear, because fear involves torment. But he who fears has not been made perfect in love.
I John 4:21 And this commandment we have from Him: that he who loves God
must love his brother also.
How do we know?
I John 3:14
We know that we have passed from death to life,
because we love the brethren. He who does not love
his brother abides in death.
One final belief:
John 8:24 Therefore I said to you that you will die in your sins; for if you do not believe that
I am He, you will die in your sins.
This is essential, my view on this is that Jesus is refering to the Father in context. He is both God and the Son of God:
John 1:1 In the beginning was the Word, and the Word was with God, and the
Word was God.
3 All things were made through Him, and
without Him nothing was made that was made.
John 10:30 I and
My Father are one.
So, Jesus is The Eternal Word, Begotten, Uncreated Creator One with the Father, Who became flesh but did not ceased from beeing God, and said: "if you do not believe that
I am He, you will die in your sins."
