God
God is sentient and can hear the prayers and fulfill the desires of the devotee. Therefore, He is sac-cid-ananda-vigraha (Brahma Samhita 5.1), the form of bliss, knowledge and eternity.

Surrender
Do not think that if we surrender to God we will be a loser. We will not lose anything except bondage, frustration and suffering. That is all we will lose.
