Paul's example in teaching the 'Whole counsel of God' Acts 20:27

Opening Prayer
Heavenly Father, we come to You in the name of Jesus Christ. We invite Your Holy Spirit—who is welcome here—to teach us, to take the exact message from Your Word this morning and plant it in our hearts. Change our lives and change the lives around us. We thank You for Your Word, for Spirit and truth. We commit this study to You and ask that You be glorified in it. In Jesus’ name, Amen.
A scripture was shared from the congregation: “Afterward, I will pour out my Spirit on all people. Your sons and daughters will prophesy; your old men will dream dreams; your young men will see visions… Even on my servants, both men and women, I will pour out my Spirit in those days.” (Joel 2).
Why Christians Should Study the Old Testament
Many Christians read only the New Testament, but the Old Testament is the foundation on which the New Testament stands. It is the story Jesus fulfils, and it reveals the God we worship.
Reasons Christians should study the Old Testament
It is the Bible Jesus read. Jesus and Paul did not have the New Testament; they taught from the Old Testament.
It reveals God’s character. His justice, mercy, holiness, faithfulness, and love are shown in rich detail.
It helps explain the New Testament. Many teachings, promises, and events are rooted in Old Testament history and prophecy.
It points directly to Jesus. Prophecies, types, and foreshadowing of His life, death, and resurrection fill its pages.
It builds resilient faith. God’s faithfulness in trials strengthens our trust today. The God who brought down Jericho’s walls is our God.
It shows God’s heart for the nations. His plan has always been to bless all nations through His people.
It teaches how God forms a people. Through stories and laws, we see how God shapes character, identity, values, and community.
It equips us for spiritual warfare. The Old Testament gives examples and principles for standing firm against spiritual challenges.
Paul’s Example: The Whole Counsel of God
Acts 20:27 — “For I did not shrink from declaring to you the whole counsel of God.”
Paul taught the full message of Scripture—promises and blessings, but also sin, repentance, and holy living. Church leaders today carry the same responsibility: to teach the whole counsel of God, not avoiding difficult truths. This protects the church from misunderstanding and misapplying Scripture.
Engaging with all of Scripture both old and new testaments deepens our understanding of God’s character and His plan for humanity.
Amen
