John 14:1

Do not let your hearts be troubled (afraid, cowardly). Believe (confidently) in God and trust in Him, (have faith, hold on to it, rely on it, keep going and) believe also in me.

When we continually and deeply ingrain our belief in the Word of God, it will be harder for us to be moved. We must practice our faith to see results and not be afraid in times of trouble. When we settle in our hearts that our response to every situation will be according to the Word of God, we will be stable and steadfast.
