Emotions and feeling are a part of who we are as christians. We can not deny them. But, we can not be ruled by them. It is a part of how God created us.
Love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self control, should be in line with Gods spirit.
When we become a christian our heart, as part of our walk with the Lord, will mature in Christ. In wisdom and knowledge of Him but also, our fruits being part of that maturing, as well. So, our feelings will not be motivated by the flesh but, by the Spirit of the Lord.
When we respond to things it will be in wisdom, not foolishness, In love, not anger, in patience, not prideful arrogance or selfish gain.
We will want to love how God loves
Therefore, we can discern between spirits.
We can correct wrong teaching.
We can evangelize.
We can be a testimony of who God is.
And the biggest thing, We will not act like the world.
