Wesley understood grace as God's active presence in our lives. This presence is not dependent on human actions or human response. It is a gift that is always available, but it can be refused.
God's grace works to create within us a desire to know God and to empower us to respond to God's invitation to be in relationship with Him. This grace enables us to discern differences between good and evil and so it becomes possible for us to choose good.
God always makes the first move in relating to humanity. He is actively seeking us!
