There are certain Biblical truths on which all believers should be grounded, established.
Too often, we hear them taught and quickly move on to other truths; not being founded on any of them.
However, Peter states twice in his second epistle (my paraphrase), “It is right (good) to be stirred up by way of reminder.” So important for us in these times.
Knowing these truths will position us to joyously receive His unending grace and the many promises enumerated in the Word.
