I could not find the word emotions listed in the ESV or KJV versions of the bible.

I had to resort to the Message Version to find the word used.

Proverbs 14:30 The Message 

A sound mind makes for a robust body, but runaway emotions corrode the bones.

What I did find about expressed emotions was listed under the spirit of man.

spirit (as that which breathes quickly in animation or agitation)

animation, vivacity, vigour

courage

temper, anger

impatience, patience

disposition (as troubled, bitter, discontented)

disposition (of various kinds), unaccountable or uncontrollable impulse

spirit (as seat of emotion)

desire

sorrow, trouble

as seat or organ of mental acts

rarely of the will

as seat especially of moral character

All of this is the character of mankind that is built into us from the beginning of creation. All of it is addressed throughout the scriptures without calling them emotions and yet we can recognize ourselves and our actions in those stories as they are played out.

What I do not see in the above list is timidity and insecurity. Just about every emotion listed under the spirit of man has an opposite corresponding emotion. It is seen easily in courage vs cowardness or perhaps vigor vs laziness.

What I do not see is pride vs humility. So the bible covers a wider range of emotions than man is comfortable admitting and categorizing. Love and hate are not listed but perhaps those should fall under the heading moral character. What is missing in all this is how the Holy Spirit differs from the spirit of man. Mankind acts out because of emotions while the Holy Spirit only enacts the will of God the Father. The Holy Spirit does not act out, we do.

While love is a choice and God is asking us to choose Him, the Holy Spirit has no choice because He is One in agreement with God the Father. He cannot choose to be anything else.

Right or wrong we have to choose. Will we allow our emotions to get the better of us, or choose to listen to God and obey? Are we going to be selfish or selfless?

John 13:23
Now there was leaning on Jesus’ bosom one of his disciples, whom Jesus loved

John 19:26
When Jesus therefore saw his mother, and the disciple standing by, whom he loved, he saith unto his mother, Woman, behold thy son!

John 20:2
Then she runneth, and cometh to Simon Peter, and to the other disciple, whom Jesus loved, and saith unto them, They have taken away the Lord out of the sepulchre, and we know not where they have laid him.

John 21:7
Therefore that disciple whom Jesus loved saith unto Peter, It is the Lord. Now when Simon Peter heard that it was the Lord, he girt his fisher’s coat unto him, (for he was naked,) and did cast himself into the sea.

Did Jesus love John more than the others?

John referred to himself as the disciple whom Jesus loved because it was his (John’s) primary identity that mattered. John was the only one of the twelve to witness the crucifixion of Jesus. He saw Jesus sacrifice Himself in a humiliating and agonizing death in John’s place. Ref. Answered in Quora

Wikipedia answered this way. Since the end of the first century, the beloved disciple has often (but not unanimously) been identified with John the Evangelist.

I appreciate that John did not say “Jesus loved me best” because Jesus loves each and everyone of us equally, even if we don’t feel that way. Listen to Peter as he questions Jesus’ instruction to feed His sheep.

John 21:21

When Peter saw him, he said to Jesus, “Lord, what about this man?”

Peter was referring to John as if Jesus was asking nothing of John except to look after Jesus’ mother as her son. Jesus had no home or earthly possessions but gave His mother to John.

Jesus gave His church into the hands of Peter to feed. Which responsibility was greater?

This is a very common human reaction of the flesh, to feel important because of what God asks of us. We look around as we grow in Christ and see greater works by others as some measure of love God has for them is greater. It is not true, but the flesh makes it feel that way.

God loves you just as much as Peter or John. What God does in us or through us has nothing to do with the quality or measure of love God has for any individual. It is a matter of His will.

That does not mean our feelings about how much we are loved are not real. They are real.
