Rev. 3:3 "Go back to what you heard and believed at first; hold to it firmly and turn to me again Unless you do, I will come upon you suddenly, as unexpected as a thief."
The Lord has the final word. He makes it very clear that if we don't get back to the basics of the faith and hold firmly to them, He will come like a thief and we will be caught unprepared. There is a real problem with over thinking the faith. Knowledge is good and we need to pursue understanding, but when our quest for knowledge and understanding robs us of our childlike faith, we have a problem.
We must never forget; we are saved by God's grace alone. God loves us and extends to us His love through His son, Jesus Christ our Lord. He is the one who purifies the heart and makes us holy. It is the righteousness of Christ that gives us an audience with God. It is what God does for us that makes us righteous. It is Christ alone who washes away our sins and casts them into the sea of God's forgetfulness. It is God who gives us the strength and power to live the life of faith. We dare not ever forget these things.
We need to passionastely remember these things and build our lives on these truths. We can never move away from these truths. We must hold firmly to them. If we don't, we will lose our bearings and not be ready when the Lord comes for us. Stay alert and never lose sight of the wondrous truth, Jesus included you and me when He died on the cross for our sins. It is by His precious blood that we have fellowship with God. He is our wisdom, righteousness and holiness before God (I Cor. 1:30).
