7 But whatever things were gain to me, these things I have counted as loss because of Christ.
8 More than that, I count all things to be loss in view of the surpassing value of knowing Christ Jesus my Lord, for whom I have suffered the loss of all things, and count them mere rubbish, so that I may gain Christ,
9 and may be found in Him, not having a righteousness of my own derived from the Law, but that which is through faith in Christ, the righteousness which comes from God on the basis of faith,
10 that I may know Him and the power of His resurrection and the fellowship of His sufferings, being conformed to His death;
11 if somehow I may attain to the resurrection from the dead.
Philippians 3:7-11
People go through many doors which do not lead to the Kingdom of God. Some try the door of good works. They say, “I can get to heaven if I only do enough good things, because God will honor all the good things I do.” It’s wonderful to do good things, but we cannot do enough good things to satisfy God. God demands perfection, and we’re not perfect. If we’re going to enter the Kingdom of Heaven, we have to be absolutely perfect. You ask, “Well, how will I ever be perfect?” We need to be clothed in the righteousness of the Lord Jesus. There is one door to the Kingdom and it’s Jesus. And we will never get to heaven unless we go His way.
