Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.
Faithful, Personal, and Persistent Care
Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. But exhort one another every day, as long as it is called "today," that none of you may be hardened by the deceitfulness of sin. For we have come to share in Christ, if indeed we hold our confidence firm to the end—Hebrews 3:12-14.
The writer of Hebrews has a serious warning for us in these verses. Some among you may become hardened by sin and fall away from the living God. For those who have heard and understood the gospel, there is no destiny more dire than this one. So how do we avoid it?
Give ourselves to faithful, personal, and persistent care for one another. We encourage and challenge one another in faith every day until the end. We need each other, the community of believers, to be engaged in our lives until this life is over or Christ returns.
In a sermon on Hebrews 3, Pastor John says, "Under the overarching goal of glorifying God, the aim of one-another ministry in the church is sustaining and strengthening faith in Christ... Sin threatens to blind and harden us all. God has appointed you to help a few others persevere in faith and fight the hardness and blindness of sin."
So we, though many, are one body in Christ, and individually members of one another.—Romans 12:5
