The Bible clearly points out that by God’s grace the apostle Paul laid the foundation which is Jesus Christ and Him crucified. All those who have come after the apostle Paul have built upon that foundation. It is with this in mind that Paul warned believers to take heed how they built upon the foundation. The foundation has been laid, and no other foundation can be laid, but each believer must carefully examine the means by which he builds upon Christ. Not only should believers take heed to their daily walk, but self-examination is also necessary in their manner of service for the Lord Jesus Christ. Each believer should search the scriptures to ensure that his efforts glorify the Lord. Far too much effort is self-serving and selfish and not God-centric. Self-examination helps define one’s motives.
God is love, but that does not mean that everything that people love is of God. Today’s verse warns believers not to love the world or the things that are in the world. God’s people are repeatedly admonished about this because believers are prone to love things and people contrary to the will of God. The Christian’s heroes are generally no different than the world's heroes. We have many Bible examples of men who loved those of whom God disapproved. Samson exemplified this in his love for Delilah (Judges 16:4). Amnon had an unrighteous love for his sister Tamar (2 Samuel 13:1). Solomon failed in this area by loving “many strange women” (1 Kings 11:1). Demas left the ministry because he “loved this present world” (2 Timothy 4:10). Unfortunately, the heart of a believer can be drawn to love things and people displeasing to the Lord. It is always important to consider the object of our love and refuse to make excuses when we know better.
