God is your shield, He is your salvation, so you should not fear what may come, because that shield is God, who will keep you from all the darts of those who want to harm you.
In Him is all my trust, because He is the God I can trust with all my heart, there is no other in whom I can trust because He is merciful and kind.
My shield is God Most High,
who saves the upright in heart.
Every day we must be right in front of the presence of God, because if we are in His ways we will be more than safe, and His shield will always be before us and will protect us at all times.
If we separate ourselves from the ways of God that are right, then His shield will be separated from us, and we will no longer have protection because we are far from His ways.
We can give an example to the psalmist David, this man trusted completely in God, He stayed on the right paths of God because He knew that being in His ways he could have protection from the Lord.
David overcame everything that came against him, but he did not do it with his own wisdom or with his own strength, but God helped him overcome all the obstacles that were before him, because he trusted in God which was his shield.
I will give thanks to the Lord because of his righteousness;
I will sing the praises of the name of the Lord Most High.
That is why this man thanked God with all his heart, praised His name, magnified Him by His wonders, by His beautiful works, and because His shield was always before him, and that shield was the Lord of hosts. Trust in God and walk confidently and He will be our shield.
