These Scriptures speak for themselves. It should make us evaluate our lives in light of how we will stand before God. We rely on His grace for sure but how we live our lives on this earth will be taken into account. We shall all stand before Christ and give an account for what we did with this life that God gave us in Christ. Let us serve Him to the fullest.
Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.
2 Corinthians 5:10
For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad.
