Which among the following three options in the service of God is the best?

[Ms. Thrylokya asked:- Which is the best among the following three options in the service of God?

I will do the service of God but defects are mine and merits belong to God.

I will do the service of God but God alone can make it successful.

I will not do it by myself but God will make me do His work.]

Swami replied:- The best option is that you shall always think “To the best of my capacity, I will serve God without aspiring for any fruit from Him in return and the rest is unnecessary for me”.
