Yes. God's love for His adopted sons is the same love He has for His unique Son, the Lord Jesus Christ.
God's love for saved sinners:
Ro 1:7 To all who are in Rome, beloved of God, called to be saints: Grace to you and peace from God our Father and the Lord Jesus Christ.
God's love for His unique Son---Jesus Christ:
Mr 1:11 Then a voice came from heaven, "You are My beloved Son, in whom I am well pleased."
The same term of endearment He calls His Son is the very same term He calls saved sinners.
See it this way---let sunshine represent God's love. Let a vine represent Christ. God's love always shines upon Christ. Christ is the very center of God's love.
Now, saved sinners are branches grafted into the vine who is Christ. Since the branches are now in the vine, now a part of Him, the very sunshine that shines upon the vine is the very sunshine enjoyed by all its branches.
God does not only love the Head, He also loves the body with the same love He has for the Head. Christ is the Head while saved sinners are His body.
