While the command of God is difficult to keep for the one who has not been born of God, it is not burdensome for that person who has been born from God. God’s child is therefore able to overcome the sinful desires of this world through faith in Jesus Christ.
The aspect of overcoming the world does not only refer to sin, but also to the trials that go along with the fight against sin. This is a world with trials and persecutions. These may weigh heavy on believers, but the verdict from God is that we have overcome—through Christ, by faith.
4 car tout ce qui est né de Dieu triomphe du monde; et la victoire qui triomphe du monde, c'est notre foi.
