Ephesians 6:13

This verse summarizes what has just preceded. It does not describe the Christian standing in victory after his or her conflict, as is clear from Ephesians 6:14-18. Probably Paul repeated himself here because of the urgency of taking up God’s provisions in view of the serious struggle we face.

The evil day in view probably describes any day in the present evil age in which the evil forces attack. A less likely possibility is that it is some day yet future that is more evil than the rest, such as the day of the Lord. Every day of temptation is an evil day for the Christian.
