FEAR NOT--2 Samuel 9:7

"And David said unto him, Fear not: for I will surely shew thee kindness for Jonathan thy father's sake, and will restore thee all the land of Saul thy father; and thou shalt eat bread at my table continually."

BACKGROUND/COMMENTARY from David Guzik (blueletterbible.org): This chapter tells of [the] gesture of kindness by David to Mephibosheth and unveils the kind of heart David had. It also illustrates the mercy of God to the underserving. One of the demonstrations of kindness shown by David to the house of Saul was to restore all the property of Saul to his heir, Mephibosheth. Because of what happened to Saul, all that belonged to him became David’s property. But, David gave it back.
In verse 5, Mephibosheth must have been terrified when messengers from David knocked at his door and demanded that he come with them to see the king. In the back of his mind he anticipated the day when David would do as other kings did and massacre every potential rival to his throne. According to the custom of the times, Mephibosheth had a lot to fear from David. Yet his fear of David was not founded in fact, only on assumption.
But, in verse 7, David removes the fears of Mephibosheth. David [had] made a covenant with Jonathan in 1 Samuel 20, promising to show kindness to the descendants of Jonathan. David gladly makes good on his promise, [even] though Jonathan is long dead. David simply promised Mephibosheth would receive what was his. Mephibosheth knew about these lands all along but he was afraid to take possession of them because it would expose him before the king. David went against all custom in showing such kindness to an heir of the former dynasty. Finally, go[ing] far[ther] beyond giving Mephibosheth what was rightly his, [David] gave Mephibosheth the honor of a close relationship with the king. 

PERSONAL APPLICATION from David Guzik (blueletterbible.org): David's grace to Mephibosheth is a wonderful picture of God's grace to us. We are Mephibosheth. We are hiding, poor, weak, lame, and fearful before our King comes to us. We are separated from our King because of our wicked ancestors. We are separated from our King because of our deliberate actions. We separated ourselves from the King because we didn't know him of His love for us. Our King sought us out before we sought Him. The King's kindness is extended to us for the sake of another. The King's kindness is based on covenant. We must receive the King's kindness in humility. The King returns to us what we lost in hiding from Him. The King returns to us more than what we lost in hiding from Him. We have the privilege of provision at the King's table. We are received as sons at the King's table, with access to the King and fellowship with Him. We receive servants from the King. The King's honor does not immediately take away all our weakness and lameness, but it gives us a favor and standing that overcomes its sting and changes the way we think about ourselves.
David's grace to Mephibosheth is also a pattern for us in serving and ministering to others. We are David. We should seek out our enemies and seek to bless them. We should look for the poor, weak, lame, and hidden to bless them. We should bless others [even] when they don't deserve it, and bless them more than they deserve. We should bless others for the sake of someone else. We must show the kindness of God to others.
