There are five of these "Trustworthy sayings" that appear in the bible, In Timothy and Titus.
Some translation are a "true saying" or a "faithful saying", But I don't think that matters a great deal just posting them in case you wanted to search yourselves.
Here are the five sayings
1 Timothy 1:14-16 (New International Version)
14The grace of our Lord was poured out on me abundantly, along with the faith and love that are in Christ Jesus.
15Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners—of whom I am the worst. 16But for that very reason I was shown mercy so that in me, the worst of sinners, Christ Jesus might display his unlimited patience as an example for those who would believe on him and receive eternal life.
1 Timothy 3:1-3 (New International Version)
1Here is a trustworthy saying: If anyone sets his heart on being an overseer,[a
] he desires a noble task. 2Now the overseer must be above reproach, the husband of but one wife, temperate, self-controlled, respectable, hospitable, able to teach, 3not given to drunkenness, not violent but gentle, not quarrelsome, not a lover of money.
1 Timothy 4:8-10 (New International Version)
8For physical training is of some value, but godliness has value for all things, holding promise for both the present life and the life to come.
9This is a trustworthy saying that deserves full acceptance 10(and for this we labor and strive), that we have put our hope in the living God, who is the Savior of all men, and especially of those who believe.
2 Timothy 2:10-12 (New International Version)
10Therefore I endure everything for the sake of the elect, that they too may obtain the salvation that is in Christ Jesus, with eternal glory.
11Here is a trustworthy saying:
If we died with him,
we will also live with him;
12if we endure,
we will also reign with him.
If we disown him,
he will also disown us;
Titus 3:7-9 (New International Version)
7so that, having been justified by his grace, we might become heirs having the hope of eternal life. 8This is a trustworthy saying. And I want you to stress these things, so that those who have trusted in God may be careful to devote themselves to doing what is good. These things are excellent and profitable for everyone.
9But avoid foolish controversies and genealogies and arguments and quarrels about the law, because these are unprofitable and useless.
I don't know whether it would be better to start an individual thread for each one, but just wondered how you relate to these verses and what impact should they have on us as Christians today are they trustworthy sayings for todays believers, have we missed the point of them, just a general chit chat about how you read them and relate to them.
