“But continue thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them;”  
2 Timothy 3:14

Then he says:
“And that from a child thou hast known the holy scriptures, which are able to make thee wise unto salvation through faith which is in Christ Jesus.”  2 Timothy 3:15
Continue in the things you have learned, knowing that the word of God which you learnt has the ability to make you wise unto salvation!
You’ve learnt about faith; saying what you want according to God’s word and remaining steadfast in what you have said despite oppositions, but right now what you are going through, it seems you need something more than faith! The word says, continue in what you have learnt, it will give you the wisdom you require to save yourself from that situation!
“Those things, which ye have both learned, and received, and heard, and seen in me, do: and the God of peace shall be with you.”  Philippians 4:9
What an idea; the Apostle was teaching the church how to do the word and he said, whatever they had learned, heard and seen in him, they should do and God would be with them to ensure they have peace concerning their actions!
What have you learnt in the word, what have you heard Jesus say, what have you seen Jesus do? Do! And God would be there to support you with more than enough peace for the situation!
Jesus spoke to a tree; speak to that letter! Jesus spoke to blind eyes; speak to your seemingly failing kidney! Do!
