Salvation to others, the eunuchs and foreigners who bind themselves to the Lord to minister to him

Isaiah 56:1-12

This is what the Lord says: “Maintain justice and do what is right, for my salvation is close at hand and my righteousness will soon be revealed. Blessed is the one who does this—  the person who holds it fast, who keeps the Sabbath without desecrating it, and keeps their hands from doing any evil.”

For this is what the Lord says: “To the eunuchs who keep my Sabbaths, who choose what pleases me and hold fast to my covenant— to them I will give within my temple and its walls a memorial and a name better than sons and daughters; I will give them an everlasting name that will endure forever.

And foreigners who bind themselves to the Lord to minister to him, to love the name of the Lord, and to be his servants, all who keep the Sabbath without desecrating it and who hold fast to my covenant— these I will bring to my holy mountain and give them joy in my house of prayer. Their burnt offerings and sacrifices will be accepted on my altar; for my house will be called a house of prayer for all nations.” The Sovereign Lord declares— he who gathers the exiles of Israel: “I will gather still others to them besides those already gathered.”

Why?

God's blessing and protection will come upon them, it is no relation to their job, identity, or other nations. Anyone who does what is right for God's salvation is close at hand and righteousness will soon be revealed.

Even the eunuchs or foreigners who keep God's Sabbaths, bind themselves to the Lord to minister to him, to love the name of the Lord.

How?

Blessed is the one who fears the Lord and does what is right before the eyes of the Lord.
