After you have asked God for something found as a promise in the Bible, meditate those Scriptures daily.

Start seeing yourself with the answer.  If you are sick, see yourself well.  If you are in lack, see yourself with abundance.  If you are having horrible family relationships, see your family loving each other in peace.

Does that sound too good to be true?  In our own abilities, it is, but in God nothing is impossible.  He responds to your faith in His Word.  He loves to give His children all of the benefits provided for them in His Word.

Hebrews 11:6  But without faith it is impossible to please him: for he that cometh to God must believe that he is and that he is a rewarder of them that diligently seek him.

Psalms 78:20  Behold, he smote the rock, that the waters gushed out, and the streams overflowed; can he give bread also? can he provide flesh for his people?

Psa 132:13-16  For the LORD hath chosen Zion; he hath desired it for his habitation.   This is my rest for ever: here will I dwell; for I have desired it.   I will abundantly bless her provision: I will satisfy her poor with bread.   I will also clothe her priests with salvation: and her saints shall shout aloud for joy. 

Philippians 4:19  But my God shall supply all your need according to his riches in glory by Christ Jesus. 

1 Corinthians 6:9-11 TPT  Surely you must know that people who practice evil cannot possess God’s kingdom realm. Stop being deceived! People who continue to engage in sexual immorality, idolatry, adultery, sexual perversion, homosexuality, fraud, greed, drunkenness, verbal abuse, or extortion—these will not inherit God’s kingdom realm.  It’s true that some of you once lived in those lifestyles, but now you have been purified from sin, made holy, and given a perfect standing before God—all because of the power of the name of the Lord Jesus, the Messiah, and through our union with the Spirit of our God.

All these Scriptures give us hope and faith.  If the lawless who practice evil can be transformed by the Word and faith in Jesus, then we have hope for our families to be healed.  Our provision is found in Christ alone, we can receive it by faith in Him.  He is our healer, our deliverer, our friend, our Savior forever.  We can trust in Him and his promises.
