"For only we who believe God can enter into his place of rest."
Hebrews 4:3
When we are in difficult situations and need a miracle, we need to determine what we believe. Is it God's Word or is it what people say or our circumstances.
What we believe produces rest and what we hear determines what we believe. If we haven't entered into rest, we are not to waste our time feeling condemned, discouraged or upset; but just realize that our faith isn't strong enough yet to produce rest.
So we must go to the Word of God and see what it says about our situation. Then get the scriptures that cover our case and feed [read, speak and meditate by hearing them over and over] on them, which will produce faith. They will get into the heart and what gets into the heart will come out our mouths. Matthew 12:34
