Unity in messaging matters. If you look at statements or press releases from any political party, you will notice that they always have a unified message. Great amounts of time and money are spent in getting their message right and making sure everyone is on board. A unified message drives policy and can even win elections.
As Christians, we also need to be unified in our messaging. To politicians, this may mean manipulating people with half-truths and euphemism. But to us, this means truly believing and teaching the same things. Paul wrote, “Now I plead with you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing…” (1 Cor. 1:10). The congregation was dividing themselves over status and moral issues (cf. 1:12-17; 5:1-5). As Paul explains, this is the result of disunity. If we are not unified in the Scriptures, we will drive a wedge between ourselves and those who need the gospel.
It is not enough, however, to simply have the same message. We must also have the same mission. What good does it do for the Lord if we preach the Scriptures but never use them to lead souls to Christ? Are we leading the lost to a life of obedience, or are we just selling them a new, exciting religious experience? The Lord commissioned His church for the work of making disciples (Matt. 28:18-20). If we are unified in this mission, we can change lives and win souls for Christ.
