20 Now to Him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us, 21 to Him be glory in the church by Christ Jesus to all generations, forever and ever. Amen. (Ephesians 3:20–21, NKJV)
It is essential that the church honors God for the abundant “power that works in us.” Notably, it is “in the church by Christ Jesus” that God’s measureless power is glorified. So, the church is essential. It is essential for the church to know how to give God honor and glory. The church honors God being faithful to obey His will. You see, Jesus died for His church to sanctify it, so it will not have “spot or wrinkle or any such thing, but that she should be holy and without blemish” (Ephesians 5:26-27). God’s will is our sanctification (1 Thessalonians 4:3). Therefore, we must love God and not the world (1 John 2:15-17). When Christians defy the will of God and love the world, Christ is shamed and God is dishonored. The church must do more than say it honors God in Christ. Christians must reflect honor for God by how we live. This is done by obeying Him faithfully. This is how to “work out your own salvation with fear and trembling” (Philippians 2:12). Such obedience is when and how God’s power works in us (Philippians 2:13). Trust God’s power. Live by faith, obeying Him “with fear and trembling.” He will work in you mightily, and take you home to eternal glory.
12 But to the rest I, not the Lord, say: If any brother has a wife who does not believe, and she is willing to live with him, let him not divorce her. 13 And a woman who has a husband who does not believe, if he is willing to live with her, let her not divorce him. 14 For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband; otherwise your children would be unclean, but now they are holy. (1 Corinthians 7:12–14, NKJV)
Should a Christian end his or her marriage to an unbeliever? The apostle gives an inspired answer to that question as he addresses this subset of “the married” (verse 10). The “rest” to whom Paul now directs his attention are identified as Christians who are married to unbelievers (vss. 12, 13). Paul addresses a marriage situation that Jesus did not personally address, namely, whether a Christian should end a marriage to an unbeliever. The answer he gives is “no” – when the unbeliever is “willing” to live with the Christian. The believer’s faithfulness to Christ blesses the family with the influence of truth and righteousness. His or her godly presence in the home helps convert the unbelieving spouse and teaches the children to be holy (1 Peter 3:1-2; 2 Timothy 1:5; Acts 16:1-2). God joins man and woman in marriage, whether or not they are believers (Genesis 2:21-24; Matthew 19:4-5). Christians have no right to end their marriage merely because they are married to an unbeliever. To do so directly violates the Lord’s command (1 Corinthians 7:10-11; Matthew 19:6).
9 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, 10 nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. 11 And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God.” (1 Corinthians 6:9–11, NKJV)
The Lord has spoken plainly and sin and its deadly effect. Sin keeps souls out of the kingdom of God. The enemies of the cross obscure this truth, deceiving blinded minds about this simple fact. Immorality prevents one from inheriting heaven. The gospel has power to save sinners of every stripe and sort. Every sinner must be convicted of the reality of his sin and its eternal death in order to come to Christ for salvation. “Do not be deceived” into thinking you can live as you please in the indulgence of the flesh, refuse to be “washed,” “sanctified” and “justified” from your sins, yet still have God’s eternal blessings. “And many of the Corinthians, hearing, believed and were baptized” (Acts 18:8). Will you? Or, will you be deceived?
