This sermon examines Genesis 21 to illustrate how Abraham's life serves as a tangible witness of God's faithfulness and character. The preacher highlights the covenant between Abraham and Abimelech, emphasizing that Abraham's integrity and honesty compelled even a pagan king to acknowledge God's presence with him. By planting trees and naming the place Beersheba, Abraham demonstrates long-term faith in God's future promises despite current uncertainties. The message challenges believers to live lives of consistency where their actions validate their testimony, thereby attracting others to Christ rather than repelling them. Ultimately, the text calls Christians to trust in the everlasting God, investing in eternity and modeling unwavering commitment to His word. Why did Abimelech approach Abraham after so many years? What did Abimelech mean when he said, "God is with thee in all that thou doest"? How should a Christian live so unbelievers recognize God's work in their life? What does it mean to be a witness through your daily conduct? Why are Christians called to match their actions with their words? What does James mean by "Show me thy faith by thy works"? Why is hypocrisy so damaging to the Christian witness? How can Christians live peaceably with all men without compromising truth? Why did Abraham confront Abimelech about the stolen well? Why were wells so important throughout the book of Genesis? What do wells symbolize in Scripture? Why are so many important biblical meetings connected to wells? What is the significance of the well at Beersheba? What does the name Beersheba mean? Why did Abraham give Abimelech seven ewe lambs? What does the name El Olam mean?
