"...strengthening the souls of the disciples, exhorting them to continue in the faith, and saying, “We must through many tribulations enter the kingdom of God.” Acts 14.22Without tribulations, there is no perseverance.
Without perseverance, there are no experiences.
Without experiences, there is no hope.
A mature faith is only possible after you have lived through tribulations.
Also, the greater the tribulations, the closer you are to the Author of faith.
