As you may already know Revelation is the only book in Bible that promises a blessing to the hearer and reader of it. As needed and as practical as the Letters from Jesus where for those then it is just as much needed now. He who hears, let him hear what the spirit says to the churches.
Please be asking the Lord for wisdom and understanding as you study His letters and for practical application for you in those things He is calling you to.
May His Word richly dwell in you,
