Hi there and welcome to the site!
According to bing, a booster is a dose of vaccine that increases or renews the effect of an earlier one; a source of help or encouragement. Those are the intents of this blog site, to re-emphasize the truths that you already know from God’s word with new perspectives, and to encourage you to walk in these truths.
Be refreshed, renewed, restored and revived as you follow and read through.
Love & ‘Blessings!
