Only one answer.[ Psalm 121]

In 2 Samuel4 v4 we read that David lived for 70years,how did he manage to survive?,as a shepherd boy ,he had killed a bear and a lion,he had fought with a giant.As a soldier he fought many battles,was hunted and hounded by Saul,survived a rebellion by his son Absolam,also he appeared to have escaped any life threatening illness,how did he survive?.In 2 Samuel 8 v6/7, we read ,and the Lord preserved David. We can take all the precautions we can, but in the end unless the Lord preserves us, we will not survive.David was very conscious of the fact that God preserved him, in Psalm 121,written by David we read the following,/The Lord shall preserve thee from all evil,He shall preserve thy soul. The Lord shall preserve thy going out and thy coming in from this day forth, and even for evermore/.I often feel vulnerable,I marvel that I have driven thousands of miles,that I was saved from drowning as a child,that I have been in many difficulties,faced many testings and temptations, how have I come through it all?well there is only one answer as far as I am concerned,the Lord has preserved me.Dear child of God you will survive, you will be kept safe,you will be brought through ,for our times our in Gods hands.Live not in fear,but trust Your God,who will preserve you,until His appointed time comes when He will call you and me home, and as we stand on heavens shore we will look back in amazement and thankfulness ,and praise God for preserving us.
A  prayer.../ Dear God we bow before You in thankfulness ,for saving and keeping us,and for the promise that You will preserve us unto Your heavenly kingdom,through our Lord Jesus Christ. Amen /
