When faith begins, anxiety ends; where anxiety begins, faith ends. Ponder these words of the Lord Jesus, “Only believe.”
As long as we are able to trust in God, holding fast in heart, that He is able and willing to help those who rest on the Lord Jesus for salvation, in all matters which are for His glory and their good, the heart remains calm and peaceful.
It is only when we practically let go faith in His power or His love, that we lose our peace and become troubled.
