I’m almost finished making my way through G.K. Beale’s A New Testament Biblical Theology: The Unfolding of the Old Testament in the New (Baker Academic, 2011). It has truly been a rewarding experience in so many ways. Some may question the sanity of reading through a 1,000 page theology book. I have found Beale’s work, however, to be not only intellectually stimulating but also spiritually moving. He unpacks the soul-thrilling message of both testaments of Scripture and like a master jeweler, brings out the innate beauty of the Gem of the Bible in all its brilliance and power. Reading Beale is reading the big picture of Scripture.
Beale also repeatedly brings application and pastoral concerns to bear. He is a theologian with a pastor’s heart, and he never fails to provide the takeaways and connect the dots from theology to Christian living. A perfect example of this is his treatment of assurance. The graphic pictured below is my attempt to reproduce a drawing on pg. 867, in an excursus on assurance, which I found incredibly helpful. I hope my readers will as well.
[Since] Christians do not reach perfection and they sin to varying degrees and in varying ways, and even the most righteous saints become increasingly aware of how sinful they are, how can they be assured that they have a true saving relationship with God? There is no simple answer to this, but there is what may be understood as a cumulative answer that comes from different angles of consideration. We may view the believer’s assurance from three angles, with each angle contributing to an aspect of assurance.
Each point of the [above] triangle represents a truth about how a Christian receives assurance.
Trust in God’s Promise of Salvation through Christ
First, God promises throughout the NT that those who place their faith in Christ and his redemptive work will receive an inner assurance that they have truly benefited from Christ’s work (the top of the triangle). [Beale goes on to discuss 1 John 5:9-15 in support of this point and continues] in this passage from 1 John assurance of true faith comes from (1) the internal witness of the Spirit; (2) the reliability of God’s word that he will give life in the Son to those who believe; (3) the confidence that God hears and answers the faithful prayers of those who ask for salvation in the Son. In fact, the purpose of the entire epistle of 1 John is to give this assurance (v. 13).
Good Works
The role of “good works” is a second angle from which to view the nature of assurance (the bottom left part of the triangle). As we have seen, one who has truly been resurrected (Eph. 2:4-6) and thus becomes a part of the new creation will inevitably and increasingly be characterized by good works (Eph. 2:10) instead of behaving like “dead people” in bondage to “trespasses and sins” (Eph. 2:1-3). Likewise 2 Pet. 1:3-4 explains that Christians possess God’s “divine power” and reflect God’s image (the “divine nature”), and on this basis they are to grow in the fruits of godliness (vv. 5-8). [Beale goes on to discuss verses 10-11 and concludes that] assurance of one’s “calling and choosing” and final “entrance into the eternal kingdom” increases with growth in doing godly things.
Accordingly, believers’ assurance of truly being part of the new creation comes as they look back at their former life and see the changes that have come about since they became Christian. Those who may have grown up from an early age as a Christian may not have such radical differences between their past and present. Nevertheless, they should not be characterized by the kinds of sins that Paul lists in 1 Cor. 6:9-10. Such people also gain a degree of assurance from this recognition. All Christians, to one degree or another, ought to be able to look back and see that they have progressed in godliness during the course of their Christian lives (recalling also that as such growth occurs, ironically so does increasing awareness of remaining sin). This observation ought to bolster Christians’ confidence that they are genuine.
Given time, if confessing believers have not changed the ungodly lifestyles of their former believing lives, then such people should not be given assurance that they have truly believed. Perhaps they are true Christians, but they should not have affirmation that they are…. Possibly, such a lack of assurance might shock them either into the reality of their faith, so that they change, or shock them into truly believing for the first time.
Conviction by the Spirit
The presence of the conviction of sin within professing Christians is a third angle from which to understand assurance… When Christians think or do unholy things, there should be immediate conflict and dissonance with the indwelling Holy Spirit, who is in the process of causing the believer to reach the goal of complete end-time righteousness. Those who are accordingly convicted about their sin will express repentance and change their sinful ways. Those who have no conviction about indwelling sin should have no conviction that they are genuine saints.
Therefore, faithful, growing Christians should receive multiple assurances from these three angles, which have a cumulative force, enhancing the overall sense of confidence about the reality of their Christian experience. What if a Christian is inconsistent in progressing in good works, and an area of life is not under submission to the Lord of the new creation? Such a person should be under great conviction about this sin, and if so, it is a good sign that the Spirit is really in the person, bringing about conviction. Such a person should not doubt knowing God, unless as time goes on the conviction over sin does not issue into repentance, a turning away from the sin being committed.
However, no confidence should exist in those who profess to believe in Jesus but who reflect no discernible change for the good in their lifestyles and who have no conviction about changing their sinful ways.
Generally, the closer people get to God as faith grows, the more such people will desire to please God by what they do, and the more they will be convicted by the remaining sin in them. As a result, they will have even greater assurance as they progress in their Christian lives. [excerpted from pp. 867-870]
I find Beale’s advice to be both important and encouraging. Even our awareness of failure can encourage us, and the very fight against sin is an evidence of being a legitimate child of God (see my post on Heb. 12 on that point).

This past Sunday I had the opportunity to fill the pulpit at our church. This was the first Sunday after the US Supreme Court made gay marriage legal nationwide. That isn’t the theme of my message but does come across in the introduction. Now, more than ever, Christians are being challenged to persevere and to keep believing. It is easier than ever to give in and to shirk from affirming Scripture as our highest authority. Hebrews was addressed to believers in a similar boat – they were faced with pressure to conform and some were slinking back from total commitment.
