24 Now to him who is able to keep you from stumbling and to present you blameless before the presence of his glory with great joy, 25 to the only God, our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and authority, before all time and now and forever. Amen. 
I think one of the things that Christians most often confuse in their Christian walk is the difference between justification and sanctification. Justification is the act by which God through the work of his Son, Jesus Christ imputes his righteousness to us, his sinful creation and thereby gives us complete right standing before him, perfect, and as our text today indicates we are blameless, though we don’t earn it or deserve it. Sanctification on the other hand is the process God uses in conforming us into his image on a daily basis.
As Jude writes to Christians in this brief letter in the New Testament he is urging the Christians to earnestly contend for the faith. This beautiful doxology in verses 24 and 25 of Jude indicates the position of justification from which we are to contend. In his letter, Jude is warning against those who had gained admission into the church and were perverting the grace of God and even denying Jesus as Lord and Christ (v. 4). Jude is urging the Christians as they fight against what is going on to continue in godliness and love toward these people, sometimes reasoning with them and in other cases “snatching them out of the fire.” (23)
There is a wonderful thing that happens to us as Christians, especially when we are able to distinguish between justification and sanctification. As we earnestly contend for the faith in the midst of some who pervert the faith, it is imperative that we always contend or fight from the position of justification we enjoy because of what Christ has done for us. All the while, there is a process going on in your life and mine (sanctification) of God conforming us into his image on a daily basis.
My encouragement today is for us to continue to earnestly contend for the faith in Christ that allows us to be kept from stumbling and be presented blameless before the presence of his glory with great joy. As we do so, let us embrace the process God has us in as we are continually transformed more and more into his image.
