Romans 15:5

“Now the God of patience and consolation, etc..] These titles and characters of God are manifestly used on account of what is before said concerning the Scriptures, and to show, that the efficacy and usefulness of them, in producing and promoting patience and comfort, entirely depend upon God the author of them: from exhorting, the apostle proceeds to petitioning; well knowing that all his exhortations would be of no avail without the power of divine grace accompanying them.

The example of God here, who bears long with his children, and is not angry soon at their offences, is a strong argument why Christians should bear with each other. If God bears long and patiently with “our” infirmities, “we” ought to bear with each other. And consolation - Who gives or imparts consolation. To be like-minded ... - Greek To think the same thing; that is, to be united, to keep from divisions and strifes. According to…”

“According to the power of Christ Jesus. Romans 15:6”

“15:5-6 live in complete harmony: This phrase (see study note on 12:16) refers to the whole orientation of how someone thinks. A mindset of harmony is important for Christian unity (see 12:3-5, 16; Phil 2:2-5).”
