I Chronicles 17:11-14
11 And it shall be, when your days are fulfilled, when you must go to be with your fathers, that I will set up your seed after you, who will be of your sons; and I will establish his kingdom.
12 He shall build Me a house, and I will establish his throne forever.
13 I will be his Father, and he shall be My son; and I will not take My mercy away from him, as I took it from him who was before you.
14 And I will establish him in My house and in My kingdom forever; and his throne shall be established forever.
4 Joseph also went up from Galilee, out of the city of Nazareth, into Judea, to the city of David, which is called Bethlehem, because he was of the house and lineage of David,
There is long period of gap between David and Jesus. Historical texts claim about 1000 years and 28 generations! But the point of our concern is thet despite this v.long time period God never forgot His promise His servant! Through Jesus, He fulfilled the promise He gave to David.
A few years is enough for our memories to fold the promises of God. We lose hope in the promises and we stop praying!
Trust God, He keeps His word…
In His time He will fulfill it.
