The question “Can anything separate us from God’s love once we are saved?” is answered by Paul in this text to the Romans.
Nothing can separate us from God’s love, so we are to live a life connected to His love. To live a life connected to God’s love is to learn to walk in intimacy daily with the God of our salvation.
Romans 8 is a chapter that should make you walk away in awe and star-struck at the love of God. We see the eternal, never-ending, unconditional love of God for those who are in Jesus, us.
