The psalmist says: “Lord, your word is a lamp for my steps and a light for my path.” Yes! Faith comes from and is strengthened by hearing and not just hearing anything but the word of God. Being(true Christian) and doing(service) are two parts of the Christian life. Ensure “to be”(that you are filled with the word and a true child of God) before you can adequately do; and ensure that you prove the former(being) by doing the latter(service).
Good morning, and remain blessed.
