In Luke 18, Jesus is giving the account of the unjust judge who gave in to the widow asking him for protection, NOT because he wanted to, but because of her persistence! Then He says this to His disciples in verses 7-8:
7 And will not [our just] God defend and protect and avenge His elect (His chosen ones), who cry to Him day and night? Will He defer them and delay help on their behalf? 8 I tell you, He will defend and protect and avenge them speedily. However, when the Son of Man comes, will He find [persistence in] faith on the earth?
We know from Romans 10:17 that faith comes from hearing (and hearing and hearing and hearing) God's Word:
17 So then faith comes by hearing, and hearing by the word of God. NKJV
Persistent faith comes from continually hearing the Word of God! We know, also, from 1 John 5:14-15, how to get God to answer our prayers!
14 And this is the confidence (the assurance, the privilege of boldness) which we have in Him: [we are sure] that if we ask anything (make any request) according to His will (in agreement with His own plan), He listens to and hears us. 15 And if (since) we [positively] know that He listens to us in whatever we ask, we also know [with settled and absolute knowledge] that we have [granted us as our present possessions] the requests made of Him.

So make the determined purpose for YOUR life to be consistent in your time in His Word so that faith will build and grow. He will answer your prayers and YOU will be found persistent in your faith, and well pleasing to HIM! AMEN! Here is an old, but very good, song from Hillsong called "Faith":
Shalom in Him!
