Those controlled by the sinful nature cannot please God.
Emotions and feelings is part of our responsibility as a christian. Handling it wisely will make us mature. We may say we are christian but if our emotions rises when we are anger, Christianity might not be seen in us because the peace of God is being lost. When we let our bad emotions like guilt, pride and selfishness take control over us, we cannot please God. He cannot come into our life if we are not open for repentance.
Let us not let our emotion overpower us. Let us give more time for God through prayer, word, fellowship and evangelism
