Romans 8:31 What then shall we say to these things? If God is for us, who is against us?
Foreknowledge speaks of God's loving intent for each believer before they were born and predestination can be likened unto a set of blue prints.
The fourth link, justification, has to do with God's judicial declaration over the sinner at saving faith: not guilty. Let the reader be reminded that justification can only occur when the sinner believes. Salvation is taught consistently in scripture as including both God's Sovereignty (election, foreknowledge, predestination, calling) and human responsibility (justified). No man can be saved lest God draws them and yet, at the same time, no man can be saved until He repents and believes on the Lord Jesus Christ.
