Do you know who the Lord is? As in the case of Matthew 7:21-23, some claim to know the Lord but do not. Jesus Christ is our Lord (Acts 2:36). Through the blessings of God's Word, found in scripture, we can know the grace of our Lord Jesus Christ (2 Corinthians 8:9) and that knowledge far surpasses any trouble or loss that we experience as a result (Philippians 3:8). However, with this knowledge there is an expectation to persuade others (2 Corinthians 5:11).
Ultimately, the most significant comfort that we can have as Christians is not only knowing the grace of our Lord but also know that He knows those who are his (2 Timothy 2:19). You will not be forgotten. Your troubles will not remain forever. You will receive the inheritance promised in Colossians 3 if you will but know the lord and serve Him (Colossians 3:24).
