Is the presence of love for Allah in the heart, more than fear of Him, considered a sin or a deficiency in faith?

In his worship of Allah Almighty, a Muslim must combine love, fear, and hope. He should worship Allah out of love for Him, hope for His reward, and fear of His punishment. The Sharia has praised those who worship Allah with these three forms of worship. Love is the foundation, and fear and hope are the wings of a bird, without which it cannot fly. If one of them is missing, its flight becomes unbalanced. If the heart is overwhelmed by a sense of security from Allah's cunning, then fear is better. If despair and hopelessness prevail, then hope is better. The most perfect state is the moderation of hope and fear, and the dominance of love.
