Isiah 61:3 helps.

Jonathan find a promise in scripture such as Jeremiah 29:11 and repeat it to God our Father. His word will not return to Him void but will accomplish everything He set it out to do. Also repeating the word outloud reiterate His promises . It also enhances and increases your own faith. I pray that your faith will fail not, that is what Jesus told Simon Peter. so look for things to change in your life as you speak the word. God's will is his word be blessed. I know it works I was in the same boat as you.
