Yes, we need how God uses the Bible to show us about Himself and about us, and it says "we first trusted in Christ," in Ephesians 2:12. Then we became new creatures with more and more totally different and new ways of thinking and feeling and loving.
Before "we first trusted in Christ" (in Ephesians 2:12), yes we could have an idea and feeling about God; however my own character had a lot to do with what I was able to feel and what I was able to conclude about whatever I thought I was discovering. But, with Jesus, my character has been changing to be gentle and humble and caring and softly and tenderly and sensitively loving and relating. And I see the Bible very differently as I grow in this.
But we do have that "God is love" (in 1 John 4:8&16). And love does have feelings!
But love has emotions and motives with actions, also.
Love can create destiny > if you love money, for example, it is your "destiny" to seek money and then suffer and not have really loving companionship and true enjoyment. And God in His love so appreciates and adores His Son, Jesus; therefore, it is destiny that our Father will make us all become "conformed to the image of His Son" (Romans 8:29). The character of His love brings His love's destiny! and this shared with us
So, yes we have feelings in God's love, but we need how God changes us in our character so we more and more get into all that is in the destiny of His love, of all our Father and Jesus will share with us in Their love.
Bringing this into line with our discussion about if religion can brainwash people, then > in religion, people still have their own character which can be their dictator. If we in selfish character love a thing or a person, we can automatically brainwash our own selves to think and feel whatsoever fits with getting what we want with that thing or person. For example, perhaps you have seen how a gambler can get a check, and right away just start talking how he or she is sure to win, this time. And if someone falls in love with someone else's charm and smooth voice and cute looks and smart talking . . . you can not talk sense to the person, though you know the charmer is a psychopath and can prove it from court records, even . . . in a number of cases. Ones can in worldly character be do-it-yourself brainwashers, here in America where we say we would never put up with our government brainwashing people > we can do it ourselves, THANK YOU!! Independence, here . . . do it your own self!!
It is so important, then, how Jesus says, "If anyone desires to come after Me, let Him deny himself, and take up his cross daily, and follow Me." (in Luke 9:23) We so have needed to deny self with its character so dictatorial and not good for us, and become new creatures in Jesus and His "faith working through love" (Galatians 5:6).
And then we have the "washing of water by the word" (in Ephesians 5:26).
And we still need this, more and more. We can so easily point our finger at "religion" and say oh we're not like that. However, we still are not perfect in our character being like Christ; so we can still fool ourselves, and not notice this because of how we are decoyed into pointing at "religion" and obviously wrong people.
But we have our Father to correct us; He can see us better than we can > so we need to actively and deliberately seek You, LORD our Father to correct us > "Furthermore, we have had human fathers who corrected us, and we paid them respect. Shall we not much more readily be in subjection to the Father of spirits and live?" (Hebrews 12:9) There are "respectable" people who have brainwashed into supposing that how their parents brought them up is all they need.
But Jesus says, "learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls." (in Matthew 11:29) We need more learning of how to be and live in His love with His light so we see things the way His love has us seeing.
