Romans 5:6

For while we were yet weak, in due season Christ died for the ungodly.

'For' -here is that message, here is the 'Love of God' that has been dispersed in our hearts, and it came through revelation.

'while we were yet weak' -'still helpless' (NASV)

'The language does not mean that we are now unable to believe God nor do what he commands. It refers to man's helplessness without the death of Christ. Men were condemned sinners, with no means of escape from sin and condemnation.' [Note: Whiteside p. 117]

'due season' -at the right time, at the strategic moment, the critical moment. (Galatians 4:4 'the fulness of the time'; Titus 1:3) 'At the time of greatest need, when nothing but His death would help' (F.F. Bruce p. 123)

"for" -instead of, or on behalf of.

'the ungodly' -this explains how God could justify the 'ungodly' (Romans 4:5). Since all have sinned (Romans 3:23), all could be called 'ungodly'.
