Slave of God needs two wings to support him in his journey to God Almighty: A wing of hope and a wing of fear.
Just as a bird needs both its wings to be able to fly and reach its destination, humans need both aspects of hope and fear in their hearts to continue their spiritual journey to God.
Hope helps them maintain trust in the mercy of God when they commit mistakes and wrongdoings. One of the attributes of Allah is Ar-Rahman--All Merciful; He is Merciful towards His creation and keeps forgiving their shortcomings and wrongdoings as long as they keep asking His forgiveness. Prophet Muhammad SAW advised Muslims not to let death approach them except with hope in the mercy of Allah in their hearts.
At the same time, humans need fear of God in their hearts to restrain themselves from excessive or persistent wrongdoings. If a person consciously keeps committing wrongs and hopes that God will forgive him, then it is "himaqa" (foolishness)--not hope.
How to develop hope and fear of God in your heart?
Read about Allah's forgiveness; study His attributes; His love for his creation, especially Muslims and you will have no choice but to have hope and love of Allah in your heart.
At the same time read about death, punishment of the grave and description of hellfire; this will generate fear and consciousness of Allah in you, InshaAllah.
May we all develop strong, and healthy wings to lead us on in our journey to Allah. Ameen.
