As for God, his way is perfect: the word of the LORD is tried: he is a buckler to all those that trust in him.
Proverbs 18:30
Words, thoughts, feelings, actions, results, your experience of life.
That’s the progression, where the starting point is: Words.
What words are you living by?
Whose words are you living by?
When your life is built upon the Word of God (the Bible), then the result will be a rock solid confidence and security that will keep you immovable and unshakeable.
