Jesus said we could move mountains (obstacles, hindrances) out of our way by using our faith and speaking to them to go.
Mark 11:22-23 Living Bible In reply Jesus said to the disciples, “If you only have faith in God—this is the absolute truth—you can say to this Mount of Olives, ‘Rise up and fall into the Mediterranean,’ and your command will be obeyed. All that’s required is that you really believe and have no doubt!"
We can speak things into existence in our life like Father God does. In Genesis, at the creation, God said and it was so:
Genesis 1:3 And God said
Genesis 1:6 And God said
Genesis 1:9 And God said
Genesis 1:11 And God said
Genesis 1:14 And God said
Genesis 1:20 And God said
Genesis 1:24 And God said
Genesis 1:26 And God said
Hebrews 11:3 By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible.
Paul then says in Romans 4:17 He (God) calls those things which do not exist as though they did.
Because words created this natural realm (the earth and everything in it including the materials that make-up our bodies), everything in this natural realm responds to spoken words. Things will respond to your faith filled words.
Jesus said in Luke 17:6 “If you have faith as a mustard seed, you can say to this mulberry tree, be pulled up by the roots and be planted into the sea and it would obey you.”
God gives each of us, as New Creation beings, the ability to change our circumstances by speaking to them in faith and expecting a supernatural result, just like God said we could have, but it's according to OUR faith.
