People who follow Christ often talk about being 'under grace' as if it is a perpetual forgiveness of their sinful past and future transgressions. Many use the term as some sort of license that allows for all sorts of ungodly behaviour. It seems to imply that once you are a Christians, you can never fall from grace.
‘Grace' actually occurs over 140 times in the bible while 'under grace' is used in just one context. (Rom 6:14-15) Paul used it to explain that Christ died and atoned for our sins so that now we are not made righteous by following laws. Instead, God having grace for us, is allowing us time to become of His righteousness through faith (Eph 2:8).
You see grace alone does not make one righteous; it is works of faith that account to our righteousness. (Gal 2:16, Rom 3:28, Jam 2:18) The true meaning of 'under grace' (charis) that Paul speaks of is like being under the blessing or gift of God.
It's like this; imagine you commit a traffic offence and have been issued a fine. Let’s say you are given a grace period of 30 days to pay the fine and then because you can't pay the fine on time, you ask for an extension of this grace period to 60 days. This means you get more time to get yourself sorted out. This is what grace is, in a sense; when we have committed an offence but are given the chance to rectify ourselves.
As it turns out, what a blessing and gift it is that Jesus paid the fine with his blood and we are now indebted to him. It means that during this period of grace we do not continue committing the same offences again or chalk up new offences. God’s grace does not undo the offences we have committed, which He has overlooked and atoned, but instead His grace gives us the chance to change our behavior through faith to be right with Him.
Now, there will come a time that it will be too late to make up for the offence. That day will be when Jesus returns. Be sure that God's grace upon you will not be in vain (Gal 2:21) because then you will truly fall from His grace (Gal 5:4) as God will render every man according to his deeds (Rom 2:6)
