Be Steadfast in Your Faith
To be sober-minded means to think rationally with sound and clear thoughts. Therefore, your mind should not be clouded by excessive alcoholism or other obsessions.
The best way to be sober is to remain steadfast in your faith in God so that you will be able to resist the devil.
Resist him, steadfast in the faith, knowing that the same sufferings are experienced by your brotherhood in the world. But may the God of all grace, who called us to His eternal glory by Christ Jesus, after you have suffered a while, perfect, establish, strengthen, and settle you. To Him be the glory and the dominion forever and ever. Amen. (1 Peter 5: 9 -11)
