"Beloved, when I gave all diligence to write to you of the common salvation, it was needful for me to write to you, and exhort you that you should earnestly contend for the faith which was once delivered to the saints." (Jude 1:3).
The Word of God does tell us that we are to contend earnestly for the faith, but what does this really mean?
There is a contending for the faith that is by the Holy Spirit in giving us the wisdom of God to combat error, but also there is a striving that is fleshly, sensual, and devilish.
This explains why that on these forums one that speaks according to the word in the right spirit can teach and instruct others, while one speaking out of the flesh can stir up contention and stife.
Please consider the scriptures below:
And the servant of the Lord must not strive; but be gentle to all men, apt to teach, patient, (2 Tim.2:24).
For where envying and strife is, there is confusion and every evil work. (James 3:16).
Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom. But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth. This wisdom descendeth not from above, but is earthly, sensual, devilish. For where envying and strife is, there is confusion and every evil work. But the wisdom that is from above is first pure, then peaceable, gentle, and easy to be intreated, full of mercy and good fruits, without partiality, and without hypocrisy. And the fruit of righteousness is sown in peace of them that make peace. (James 3:13-18).
Those that walk in the flesh walk in strife.
For you are yet carnal: for whereas there is among you envying, and strife, and divisions, are you not carnal, and walk as men? "1 Corinthians 3:3).
"Those who have received the doctrine of this common salvation, must contend for it, earnestly, not furiously. Lying for the truth is bad; scolding for it is not better. Those who have received the truth must contend for it, as the apostles did; by suffering with patience and courage for it, not by making others suffer if they will not embrace every notion we call faith, or important. We ought to contend earnestly for the faith, in opposition to those who would corrupt or deprave it." (Matthew Henry)
