The apostle John has previously considered the result of suggestion, faith, fidelity to the precepts and practice of fraternal mercy, here defined in its very nature: not only is the invitation and tie union but, since God is love, stay in love is dwelling in God himself.
This essence is the relationships established between the person who has received Christ into his heart and God through grace.
He is the living embodiment of Christ's prayer: May the love with which you loved me may be in them and I in them.
Perseverance in love and union with God depends on fidelity to the commandments and ordinances of the Lord, as we already mentioned. He who abides in love, brotherly kindness, remains in God and God in him, for he who loves is born of God.
That is, without tenderness fraternal communion is not given to God for the forgiveness of sins.
The sign that brotherly love is brought to perfection that will have boldness in the Day of Judgment.
In this is love perfected with us, that we may have boldness in the Day of Judgment; because as He is, so are we in this world. 1 John 4:17 Reina Valera 1960 Bible

The fear of being condemned in the Day of Judgment is inappropriate with grace.
And the larger the business, the more confident we are in the day of celestial Coming of Jesus Christ in the end of the world, because only perfect grace has the power to remove all fear.
The perfection of love is reflected in the bold confidence in the blessed courage, in the intimate security it engenders in us the grace of brotherhood.
This grace makes the vital relationship between God and the person who has received Christ into his heart, which will slowly eliminating the doubts that may exist in the hearts of those who believe in Christ, the uncertainty of trial.
