vs 10b They perish because they refused to love the truth and so be saved.
The love of the truth is a mark of one who is a genuine believer.
So many people have heard the gospel, the Word of Truth and yet still they have chased not to believe it. They have rejected Jesus Christ as the Lord and Savior and as a result they have left themselves open to the influence and lies of satan. Those who go to hell do so because they reject truth. They willfully choose to love their sin and hate the gospel and as a result God hardens their heart and allows them to be deceived. In other words over time God will harden the hearts of those who persistently reject His truth.
We think of that and we think of all the people who are not “in the church,” but the truth is some of these people live inside the church. So many who profess to be Christ-followers persistently reject God’s truth and reject it’s influence on their lives. You see the love of truth constrains us to follow Christ. We allow the Holy Spirit to change us and make us in the image and likeness of Christ. We pursue Truth, like the deer that pants for water in a dry and thirsty land.
Our love for Christ (the Truth) and our willingness to allow Him to change us from the inside out is one of the marks of a true disciple.
