What to read after Return to Gospel?

Hello, I'm your servant Min Shalom.
The essence of our faith. These days, the beginning of the gospel of Jesus Christ is considered more brilliant and precious. The world is running faster towards the end. The division is further tarnishing and degenerating the gospel as if it had sensed its end was near, and spreading constant temptation (Adm. 4:4) so that Jesus' gospel could never be engraved on its heart.
At a time like this, when it is not enough to love only you, you must be more awake so that you will not be distant from you or lose your love for the first time. Even those who believe in Jesus can fall at any time, so they must be more deeply rooted in the gospel.
This book is the property of faith and the confession of faith that I wrote while struggling to protect my faith when I was in the army. The reason why I re-edited it and published it again was to reflect on the nature of my faith and to wake up many people and to convey the full gospel, I planned and practiced it with the impression of the Holy Spirit.
Dear brothers and sisters in Christ Jesus, I sincerely hope that this small book will convey the great love of the Lord, how much he loves you, how much he wants, how much he waits, and how much he longs for you.
Listen to the voice of the Lord who calls us. In response to the invitation of the Lord, who invites us with that eternal love and leads us from glory to glory, let us all go before the Lord and before the gospel again!
Then I'll meet you in heaven!
