The Apostle Paul is exhorting the church in Rome to receive such Jewish converts into their fellowship even though they may not be a fully practising Christian. The reason given is that God has received such a one. We are not to reject him. Rather, to give them time to understand the faith more fully. Meanwhile, extend to them the right hand of fellowship, accord to them Christian love and kindness though there are these differences. Be willing to accommodate them.

The believer is called to be vigilant to guard against yielding to sin. The Apostle Paul is exhorting the believer by a command from God to personally take charge of his life that it be guided by God’s Word and His Spirit. He makes a contrast that the believer cast off every work of darkness and walk in the light, in holiness.

The believer is to cherish the freedom that he has received being freed from the bondage of sin through the cleansing blood of Jesus Christ and to keep himself pure for he has been redeemed by a great price paid as the Apostle Paul explains in Ephesians 2:1-5 And you hath he quickened, who were dead in trespasses and sins; 2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: 3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others. 4 But God, who is rich in mercy, for his great love wherewith he loved us, 5 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;).

To be honest is to reject that which is false. The LORD hates falsehood and delights in truthfulness for the God of the Bible is a God of Truth, in Him is no lie (Hebrews 6:18). Truthfulness is the manifestation of God’s character. An honest Christian is a true reflection of the God he/she professes to follow. An honest man exemplifies human nature in its highest forms, for men of character are the conscience of the society to which they belong. Men of genuine excellence in every station of life, are men of industry, of integrity, of godly principle, of sterling honesty of purpose. Although genius always commands admiration, but character most secures respect. [Character Sketches for Boys and Girls by Henry Davenport Northrop]

A serious indictment is given here for the believers to repent of their sins. This is a call to self-examination and confession of sins. Let sin be rid of and let holiness be our portion. The Bible character Lot, the nephew of Abraham, was vexed by the immorality and sin-sickened of the inhabitants of Sodom. Yet, he tarried there hoping to make an earthly gain by his association with the men of Sodom. He suffered great loss. His wife was judged by God. She turned into a pillar of salt. His daughters were so plagued by the ill-moral standards of the city, they committed incest with their father.

The Apostle Paul warns the believers against spiritual slumber and tardiness. He exhorts the church to spiritual alertness and vigilance. Our Lord Jesus is returning soon to take the church to glory. When Jesus comes, He will reward His faithful servants. We are to make sure that when the trumpet call comes, we will be caught up to heaven just like the godly Enoch who was taken to heaven physically without seeing death.
