You are right, the last minute tells us to stop and think about everything. A man can at the last minute repent of all his mistakes and become a righteous man. An example of this is the thief on the cross on the right side of Christ when there was a crucifixion on Good Friday. He repented at the last minute and received forgiveness from Christ. The first person to enter heaven was a sinner who at his last minute repented of his sins and received forgiveness from God and entered heaven.
