Truth through Ephesians

[Eph 1:13 KJV] In whom ye also [trusted], after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,

The truth of the gospel seals believers with the Holy Spirit.

[Eph 4:15 KJV] But speaking the truth in love, may grow up into him in all things, which is the head, [even] Christ: ...

Truth in Christ benefits His body, the church.

[Eph 4:21 KJV]  If so be that ye have heard him, and have been taught by him, as the truth is in Jesus: ...

Truth in Christ will change your life as the old man is replaced with a new man, a more truthful man.

[Eph 4:25 KJV] Wherefore putting away lying, speak every man truth with his neighbour: for we are members one of another.

As the sin of lying affects those around you, the righteousness of truth will also affect others for the better.

[Eph 5:9 KJV] (For the fruit of the Spirit [is] in all goodness and righteousness and truth;)

The truth is light in a world that practices and celebrates darkness.

[Eph 6:14 KJV]  Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;

The truth is foundational to a life lived for Christ.
