But to have such a mercy of God, you also need to have your mind turned toward Him in prayer. Your thinking should be toward the God, you need to become His devotee, you need to offer obeisance's to God and worship Him always. When you shall become absorbed in God in such a way then you shall become eligible for the God's mercy & He shall always Bless you.
Worshipping the God, becoming His devotee, doing service to God & making Him your only savior shall take you toward Him. Once you are eligible for such a mercy of God then He shall shower all His blessings on you. Below verses of Bhagwat Gita explain that only :
"samo ’ham sarva-bhutesu
na me dvesyo ’sti na priyah
ye bhajanti tu mam bhaktya
mayi te tesu chapy aham" (Bhagwat Gita: Chapter Nine verse 29)
"Sri Krishna said: O Arjuna, I envy no one, nor am I partial to anyone. I am equal to all beings. But whoever renders service unto Me in devotion is very dear to Me, and I am also very dear to him."
mam ekam saranam vraja
aham tvam sarva-papebhyo
mokshayisyami ma suchah" (Bhagwat Gita: Chapter Eighteen verse 66)
"Sri Krishna said: O Arjuna, Abandon all varieties of religion or Setting aside all meritorious deeds, just surrender unto Me. I shall liberate you from all sins. Do not fear."
"ananyas cintayanto mam
ye janah paryupasate
yoga-ksemam vahamy aham" (Bhagwat Gita: Chapter Nine verse 22)
"Sri Krishna said: O Arjuna, But those who always worship Me with exclusive devotion, meditating on My transcendental form—to them I carry what they lack, and I preserve what they have."
man-maya mam upasritah
puta mad-bhavam agatah" (Bhagwat Gita: Chapter Four verse 10)
"Sri Krishna said: O Arjuna, Being freed from attachment, fear and anger, being fully absorbed in Me and taking refuge in Me, many, many human beings in the past became purified by knowledge of Me—and thus they all attained transcendental love for Me."
"patram puspam phalam toyam
yo me bhaktya prayacchati
tad aham bhakty-upahrtam
asnami prayatatmanah" (Bhagwat Gita: Chapter Nine verse 26)
"Sri Krishna said: O Arjuna, If one offers Me with love and devotion a leaf, a flower, fruit or water, I will accept it."
dadami buddhi-yogam tam
yena mam upayanti te" (Bhagwat Gita: Chapter Ten verse 10)
"Sri Krishna said: O Arjuna, To those who are constantly devoted to serving Me with love, I give the understanding by which they can come to Me."
So from the above verses of Bhagwat Gita it is very clear that when God shall shower His blessings on you then He shall provide you everything in life & shall always protect you. The only thing is that you should become eligible for such a mercy of God by becoming His devotee. So let God's grace and mercy always shine upon your lives. May God Always Bless You.
Jai Sri Krishna
