“For freedom Christ has set us free; stand firm therefore, and do not submit again to a yoke of slavery”. This is one of Paul’s main points in Galatians. We’ve been set free from slavery to sin, offered an inheritance in the house of God as joint-heirs. “Through love serve one another” is Paul’s guidance for us.
“Let us do good to everyone, and especially to those who are of the household of faith”. This is how we show our love for God.
