True worshiper

"But the hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for the Father is seeking such to worship Him." John 4.23

God the Father seeks true worshipers. But how to distinguish between the true and the false worshipers? The true worshipers will worship God - the Father - in spirit and in truth. In spirit means to worship with an intelligent and balanced faith. 
God is intelligence and wisdom, so why would He accept an emotion based worship? 
In truth means to worship Him through His Son Jesus, The Truth.

Flesh vs. Spirit

"For the mind set on the flesh is death, but the mind set on the Spirit is life and peace" Romans 8.6

To lean onto the flesh means fulfilling the desires of the heart, which is the source of misleading and prohibited feelings.
To lean onto the Spirit is to deny the feelings of the heart and practicing the discipline of faith.
The flesh hates discipline, order, justice, Bible, Law, fear of God, perseverance, Commandments, and everything else that pertains to spiritual values ​​and that are contrary to the emotions of the heart.

WHAT SHALL I RENDER

"What shall I render to the Lord for all His benefits toward me?"       Psalm 116.12

I love You, I praise You, I thank You, hallelujahs and songs filled with emotions are good. In fact, they do more for the person who is worshiping then for God, Himself. 
What God really wants is for His children to HONOR Him and for His servants to RESPECT Him.
I think that He must be tired of listening to so many empty words spoken by people in churches.
Obedience and the practice of His Word are worth more than a million words of praise. It shows FEAR OF THE LORD.
That is what we must give Him in gratitude.

LOVE

" 'You shall love the Lord your God with all your heart, with all your soul, with all your strength, and with all your mind,' and '(love) your neighbor as yourself'."    Luke 10:27

If the love God is asking us for had anything to do with the emotions of the heart, it would be impossible to love Him. Because how could you feel love for the Unknown? 
How could you demand any emotions from your heart?
The love mentioned above refers to a thought, followed by an action.
Biblically speaking, love and giving walk hand in hand. For God so loved the world that He gave His only begotten Son... John 3:16
Therefore, love is giving, caring, respecting, helping, overall it is doing something for someone you love. 

Feast

"Therefore let us keep the feast, not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth."

1 Corinthians 5:8

The Lord Supper is a celebration of the live presence of the Lord & Savior Jesus Christ in us. For this reason, it must be taken with a free conscience of all emotions and guilt.
