God calls people into different works. In the midst of this diversity, a common thread unites all the work—men ought to do all they do to the glory of God.
Men tend to fret over the motives behind others’ actions. Instead, men should trust the Lord to deal with the motives at the judgment seat of Christ.
How would making your motive match the Lord's motive change how you approach the Christian life (from witnessing to praying to Bible reading and so on)?
The word church is frequently and almost exclusively used to refer to the building where the saints meet. A careful study of the scripture reveals that the church actually consists of the people. However, this passage also teaches that there is a proper behaviour when and where the saints assemble. It is a holy time meant to be accompanied by sobriety. In fact, believers are instructed that everything is to be done “decently and in order” (1 Corinthians 14:40). As we approach the time of preaching or instruction, we should be ready to hear and slow to speak (Ecclesiastes 5:1-3). During the invitation, as the Lord moves in our hearts to repent and do right, we should pay [keep] what we vow [promise] (Ecclesiastes 5:4-7). Always keep in mind that the house of God is the pillar and ground of the truth and we should treat it as such.
