No believer should knowingly marry an unbeliever (2 Corinthians 6:14). Additionally, the unmarried should look for other strengths and weaknesses in a prospective spouse before agreeing to marriage. Oftentimes, these strengths and weaknesses can be seen by interaction with the other’s parents. Isaac lied about Rebekah (Genesis 26:6-7) just as his father Abraham lied about Sarah (Genesis 12:10-13; Genesis 20:1-2). Solomon’s weakness for women (1 Kings 11:1) was first witnessed in his father David (2 Samuel 11:1-4). Rachel learned deception (Genesis 31:32-35) by watching her father act deceptively (Genesis 29:25). A careful observation of parents can reveal prospective problems in a future spouse.
The Bible records Jonathan and David's strikingly close friendship like that of siblings. Regardless of this cherished relationship, Jonathan's father, king Saul, feared and despised David. Both king Saul and his son died during battle, thus paving the way for David to ascend to the throne of Israel. Once David became king, he sought for an opportunity to show kindness to any of Jonathan’s remaining family members. After searching through the land, it was discovered that Saul and Jonathan had one remaining descendent (Mephibosheth). David sent for Mephibosheth and told him his intentions of showing him the kindness normally reserved for a member of the king's family. This act of kindness included the restoration of his family’s property. David’s kindness also made provision for Mephibosheth to eat at the king’s table (2 Samuel 9:7), “as one of the king’s sons” (2 Samuel 9:11). David’s kindness meant that Mephibosheth would be viewed and treated as a son. This demonstration of kindness illustrates God's act of kindness toward His beloved children through Christ Jesus.
