What is Biblical Counselling and who do Christian churches make such a big deal of it?

Description of Biblical Counselling

Perhaps the shortest description of Biblical Counselling is illustrated in 1 Thessalonians 5:14.

we urge you, brothers, admonish the idle, encourage the fainthearted, help the weak, be patient with them all.

1 Thessalonians 5:14

Biblical counselling can be described as godly men and women bringing situation-specific application of Biblical truth to one another.

Tools of Biblical Counselling

Biblical counselling is not just for some hyper-specialised kind of pastor, elder, or teacher. Instead, any Christian with a good knowledge of Scripture and a personal commitment to the goodness of godly living is able to bring situation-specific application of Biblical truth to another.

I myself am satisfied about you, my brothers, that you yourselves are full of goodness, filled with all knowledge and able to instruct one another.

Romans 15:14

Rationale of Biblical Counselling

Christians can have greater confidence in Biblical Counselling than the best of worldly counsellors. The reason for it is because we have been enlightened about God’s grace and God’s knowledge. Every Christian is evidence that God very effectively changes the way we think and act. And on top of all of this, Jesus makes sure that we will never lack anything to remain guiltless until He returns. Ultimately, our rationale for Biblical Counselling rests firmly on the faithfulness of God to complete the work He began when He called us to Himself.

All of this is simply a restating of 1 Corinthians 1:4-9

I give thanks to my God always for you because of the grace of God that was given you in Christ Jesus, that in every way you were enriched in him in all speech and all knowledge—even as the testimony about Christ was confirmed among you—so that you are not lacking in any gift, as you wait for the revealing of our Lord Jesus Christ, who will sustain you to the end, guiltless in the day of our Lord Jesus Christ.
God is faithful, by whom you were called into the fellowship of his Son, Jesus Christ our Lord.
