‘The day of the Lord’ – (vs2) is the great and the terrible day spoken of all through the Old Testament when Yahweh will come to save His faithful ones and will come to punish the those who rejected His kind offer of forgiveness through His Son.
It is a day with two distinct perspectives depending on one’s faith trajectory. For some, it’s a great day, a day to be longed for and anticipated, and yet for those who rejected God’s Son as their Lord & Saviour, its a terrible day.
This day will come suddenly, will come when people aren’t expecting it (vs3). To some the suddenness is negative & not welcomed – ‘like a thief’. Yet for others the suddenness is positive & welcomed like a pregnant woman suddenly going into labor. (vs3)
These contrasting ‘suddenly’s’ refer to the contrasting experience on ‘the day of the Lord’ depending on ones state of faith.
But this coming day in all our futures isn’t to be feared for those who are God’s children, ‘children of the light’ (vs4-5), for we have been transferred from the kingdom of darkness into Jesus’ kingdom (Colossians 1:13) which is the kingdom of light as Jesus is Himself, the light of the world (John 8:12).
Knowing these things, believing these things helps us to be at peace with our future, and helps us to stay alert, awake, sober ready for Jesus’ return. (Vs6)
Knowing these things, believing these things helps us to choose to keep putting on the breastplate of faith and love and the helmet of the hope of our salvation to protect us until that day (vs8).
We who have believed in Jesus Christ, we are not destined for wrath but for salvation through our Lord Jesus Christ, the one who died in our place for our sin so that we might live forever with Him (vs9).
So let’s encourage one another and build one another up!
And let’s reach out to all we know with the good news that those who put their trust in Jesus, those who ask Him to forgive them of their sins, will be forgiven and then this THAT DAY will be the first of an eternity of GREAT DAYS.
