Psalm 119:43-45 KJV
And take not the word of truth utterly out of my mouth; for I have hoped in thy judgments.  So shall I keep thy law continually for ever and ever.  And I will walk at liberty: for I seek thy precepts.
Delighting in God’s words like the Psalmist is a soulful living. Is something that you’ve accepted on your own against all doubt to stand for the truth and uphold righteousness till you depart to meet your master. Many of us have different calling but we are all called by one Master which is Christ Jesus of whom we will give account of our living here on Earth.
It is not easy to study God’s word and have it in you save for the help of the HolySpirit because that same truth you know can be taken off you within a twinkling of an eye if such one is not careful.
In summary of the verses above; The word of God is Truth, the HolySpirit our comforter is to guide us into all truth even though we are living in a decitiful world. To keep God’s law continually you have to make yourself an ardent Bible reader and study of God’s word. Knowing the truth helps you exercise freedom and walk in liberty. (John: 8 vs. 32).
What the Devil is fighting everyday is the truth and as many that knows it, when the truth departs from you you won’t seek God’s judgment over any issue, even when you are wallowing in sin your heart will refuse correction and become reprobate. You still feel unworthy and sober now when you are wrong and seek God’s forgiveness when you unknowingly commit sin because you know the truth and God’s word in you judges you but when this truth is taken away from you no remorse is felt rather the heart deepens in wickedness and unrighteousness.
I pray as we delight more in God’s word we won’t loose the truth we discover but use it to reach out to others.
