“It is possible to endure in this life but to do it in a self-righteous, resentful survivor-spirit that is self-pitying and angry at those who do not shoulder the burden with you while being inwardly proud of your grit. Instead of the fruit of the Spirit, there is bitterness and joylessness. In truth, God may not consider this kind of life to be one of endurance, and certainly not one of “great endurance” (2 Cor. 6:4). Paul endured with the inner graces of the Spirit. Sweet endurance is what the Scripture here enjoins… Sweet in-Spirited endurance testiﬁes to the reality of Christ and that He is worth our trust and service.”
2 Corinthians, p. 134.
