God’s grace is just like the shower of rain and the sunlight. You must do some sadhana (spiritual practice) to acquire it; like keeping a pot upright to receive the rain, or the sadhana of opening the door of your heart, so that Sun may illumine it. Pray for grace and do little sadhana. Grace will set everything right. Its main consequence is Self-realisation (Atma sakshatkara); but there are other incidental benefits too like a happy contented life, and a cool courageous temper, established in unruffled peace (shanti). The main benefit from a jewel is personal joy but when one has come to the last coin in the purse, one can sell it and start life again! That is an incidental advantage. The plantain tree has bunch of fruits as its main gift! But its leaves, soft core of its trunk, flower bud, etc. are subsidiary items with profitable use. This is the nature of grace. It fulfils a variety of wants.
