A decision must be made to lay down all self-interests and we must deny ourselves, take up our cross and follow Jesus. We must a final decision to either follow Jesus or the devil, we cannot follow both. Listen to Jesus' parable of the great dinner and listen to the excuses made for not seeking Jesus. There's nothing more miserable than trying to follow Jesus and our self-interests, the result is always hard-heartedness and backsliding.
Here's what Jesus said in Luke 14:26-27 “If anyone comes to me and does not have single-minded loyalty to Me over his father and mother, and wife and children, and brothers and sisters, and yet even his own life, he is not able to be My disciple. And whoever does not bear his own cross and come after Me is not able to be My disciple” (Lavender's New Testament).
Self interest causes us to be lukewarm with Jesus and will result in us being vomited out.
