You see, as long as we are living here on this earth we would always be faced with giants who would taunt you and I and attempt to curse the blessings we have received. Their senseless attempt is to try to enslave our mind, to hold us hostage/prisoner to doubt, fear and even death. But here is a strategy. Never attempt to go up against your giants to fight with a view of gaining your victory doing it on your own or in your own strength. The battle is not yours, the battle is the Lord's and it is He who shall fight for you and give you the victory!
David's elder brothers (1 Samuel 17:13) I believe were going about trying to gain their victory in their own strength and leaving God out of their plan, hence their fear and weakness. Saul himself tried to robe David in his physical armour to which David politely refused and said to Saul, "I cannot go [to battle] with these, for I have not proved them." (1 Samuel 17:39) In essence David gave the recognition and praise to the one who had always helped him out of his troubles, the one whom he was once again willing to trust and to step out in faith and to show to all that were looking on at the outcome, that no matter what he faced, God will once more be his strength and shield!
He proved the truth of God's word that he would win the battle by putting on and wearing the whole armor of God (Ephesians 6:13-18) knowing also the "the weapons of our warfare [that which we do spiritual battles with] are not carnal [that is, of the flesh, or man's thoughts and ways] but are mighty through God to the pulling down of strongholds. Casting down imaginations, and every high thing that exalteth itself against the knowledge of God.." ~ (2 Corinthians 10:4-5)
Remember this word today, that as you go through life and you face your giants, that the same God that brought David out, is the same God who delivered me and who will deliver you too! In the court David was only looked at as Saul's physician (minstrel) but in the camp he was Israel's champion and the one whose unparalleled bravery going up against a huge Philistine giant with a sling and a stone, brought about a glorious victory which gave God's Israel the advantage against their enemies.
Have a great weekend everyone!
