Philippians 3:7-14 But whatever were gains to me I now consider loss for the sake of Christ. What is more, I consider everything a loss because of the surpassing worth of knowing Christ Jesus my Lord, for whose sake I have lost all things. I consider them garbage, that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which is through faith in Christ—the righteousness that comes from God on the basis of faith. I want to know Christ—yes, to know the power of his resurrection and participation in his sufferings, becoming like him in his death, and so, somehow, attaining to the resurrection from the dead. Not that I have already obtained all this, or have already arrived at my goal, but I press on to take hold of that for which Christ Jesus took hold of me. Brothers and sisters, I do not consider myself yet to have taken hold of it. But one thing I do: Forgetting what is behind and straining toward what is ahead, I press on toward the goal to win the prize for which God has called me heavenward in Christ Jesus
Paul writes that he wants to know Christ. That sounds really good to me as well. How do we do that Paul? Where is the instruction manual, the directions written in Cantonese? While it is true we have been given the Bible, and from that book we can learn much about Christ, I believe what Paul was saying was that he wanted to experience Christ, not just to know about Him. So how do we do that? Go and learn. Paul says to participate in His sufferings. Jesus loved and cried and denied Himself for the good of other people.
By doing the same thing, by denying ourselves and putting ourselves out there to serve and possibly be hurt by other people; this is how we know Christ.
