John Gill's Bible Commentary Ver. 2. Grace be to you, and peace from God , &c.] (See Gill on Romans 1:7).
Matthew Henry Commentary
Verses 1, 2 - All Christians must be saints; if they come not under that character of earth, they will never be saints in glory. Those are not saints, wh are not faithful, believing in Christ, and true to the profession the make of relation to their Lord. By grace, understand the free an undeserved love and favour of God, and those graces of the Spirit whic come from it; by peace, all other blessings, spiritual and temporal the fruits of the former. No peace without grace. No peace, nor grace but from God the Father, and from the Lord Jesus Christ; and the bes saints need fresh supplies of the graces of the Spirit, and desire to grow.
