For it is by God’s grace that you have been saved through faith. It is not the result of your own efforts, but God’s gift, so that no one can boast about it.  God has made us what we are, and in our union with Christ Jesus he has created us for a life of good deeds, which he has already prepared for us to do.
( Ephesians 2:8-10 https://bible.com/68/eph.2.8-10.gnt )

There are four essentials of grace for every follower of Jesus:

Grace is unassisted. We can’t assist the work of Christ’s grace without diluting or diminishing it.

Grace is unmerited. When we detect some unrighteousness in our lives, many of us think we have to pump up our grace again with good works. No, Christ’s grace toward us is totally unmerited, never partially so.

Grace is unchanging. God’s grace does not apply less on the days we pray less. It doesn’t work that way. Even His warnings against sin are a sign of His loving grace.

Grace is unending. Neither the Father nor the Son will be unfaithful to the covenant they have made. It will last through eternity, never to be broken, so as we remain hidden in Christ, we remain in covenant with the Father—we are thus safe and secure.
