There is no act, no decision, no prayer, no work of any sort which you can perform to keep yourself in the faith. It is all accomplished by the grace of God through the power of the Holy Spirit, who has revealed to us that He desires and chooses to work in us only through the Word of God. Therefore the truth is that only those who abide in the Word are truly disciples of Jesus because that is how He has chosen for this thing called faith and salvation to work. The truth , in which we shall be kept, is sound doctrine. If you do not believe the truth , you do not possess the freedom which the truth gives.
Sound doctrine is the truth .
It is what the Bible teaches. Contrary to the expressed conviction of many people, how you feel about the truth is less significant than t he truth itself . It is not whether you like the truth , or feel all warm and squishy about the truth that makes the difference. It is only whether you believe it. Faith, and faith alone, receives the forgiveness of sins and life and salvation.
