Unfortunately, people use that beautiful word wrongly nowadays by referring Doctrines of the Bible as indoctrination. By definitions, indoctrination means the process of teaching a person or group to accept a set of beliefs uncritically while doctrine means teachings.
Doctrines mentioned in the Bible could be false (Ephesians 4:14) or sound (Titus 2:1). Our focus of today's teaching is on the sound doctrine which reflects the intent of God via His Word. Out of many sound doctrines in the Bible, the doctrine of Redemption is an essential course because Redemption is a big thing!
Psalm 107:2 says "Let the redeemed of the Lord say so, whom he hath redeemed from the hand of the enemy;"
Through the Redemption on the cross, all our debt is paid in full. Thus, we are free from any bondage. We are redeemed by the blood!
John 19:28-30 (NKJV)
