What is Paul telling Timothy in the chapter? What’s the point of his message here? Where is Paul when he wrote this epistle? He was in jail. Are you aware that when Christians were arrested for practicing Christianity that they were given the opportunity to deny Christ in order to escape punishment? That’s precisely what Paul is warning Timothy not to do here. It’s the same exact message that Jesus gave His disciples in Matthew 10 which is why Paul is quoting Jesus from Matthew 10.
Some flee persecution and are none the less in Christ.
Some are appointed to honour Jesus in persecution and are given the grace to bare it.
In neither case their eternal life is threatened - the blood of Jesus avails for them because of who they are - not what they do.
Paul is telling Timothy to remain in his appointed path and not deviate from it.
When we are faithless He is faithful for He cannot deny Himself.
The vastness of the Love of Jesus is not commonly understood - He is not watching for us to fail and threatening to punish is if we do. He is a loving Shepherd who gathers the flock, even leaving the 99 and going to rescue the one from the danger of sin because we are His sons and daughters who He loves and has chosen to fellowship with eternally.
Consider Isaiah 1...
18 “Come now, and let us reason together,”
Says the Lord,
“Though your sins are as scarlet,
They will be as white as snow;
Though they are red like crimson,
They will be like wool.
19 “If you consent and obey,
You will eat the best of the land;
20 “But if you refuse and rebel,
You will be devoured by the sword.”
Truly, the mouth of the Lord has spoken.
In 18 the promise of forgiveness and salvation is already assured eternally.
In 19 the consequences of obedience or otherwise results in Blessing or Calamity
IN THIS LIFE.
The two are separate issues that should not be confused.
The Gospel of the Kingdom is Good News not bad news.
