Ever since I truly was taught the Bible, and then began to study it myself - thus growing closer in my relationship with the Lord Jesus, the phrase "Christ is sufficient and love is enough" became a foundation upon which to build my life. To help explain in part, I like to think back to the words penned by the apostle Paul in Philippians 3:7-11, "But whatever was to my profit I now consider loss for the sake of Christ. What is more, I consider everything a loss compared to the surpassing greatness of knowing Christ Jesus my Lord, for whose sake I have lost all things. I consider them rubbish, 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 and is by faith. I want to know Christ and the power of his resurrection and the fellowship of sharing in his sufferings, becoming like him in his death, and so, somehow, to attain to the resurrection from the dead."
If you take the time to read the verses prior to the ones mentioned above, you will see that Paul is making a brilliant argument about the confidence that we as people put into everything else other than Christ. Paul himself was a young man with great reason to boast in the flesh. He was a devout Pharisee, a fine-standing man man in the eyes of the religious leaders (a "Hebrew of Hebrews", vs. 5), a zealot bent on persecuting the believers of Jesus and doing so in the name of God. He was everything that a young Hebrew man of the time could dream of becoming, yet one encounter with the risen Lord completely turned Paul's life on end. And here is where the "Love Is Enough" concept can clearly be made evident.
