God gives his life for his sheep and we can verify an example of this in his word where he shows us that he gave his son Jesus Christ to die on a cross crucified out of love for us, his creation.
Those who really believe this psalm is to say to these words of conviction that David also made a lifestyle of him, he will live firm, calm and with peace on this earth.
Psalm 23
23 Jehovah is my shepherd; I will lack nothing.
2 He makes me lie down in green pastures;
Beside still waters will shepherd me.
3 He comforts my soul;
He will guide me in the paths of justice for his name's sake.
4 Though I walk through the valley of the shadow of death,
I will fear no evil, because you will be with me;
Your rod and your staff will give me encouragement.
5 You prepare a table before me in the presence of my adversaries;
You anoint my head with oil; my cup is overflowing.
6 Certainly good and lovingkindness will follow me all the days of my life,
And I will dwell in the house of the Lord for long days.
(RVR1960)
Christians who believe in God must fully trust that the word of God is true and that he always acts in accordance with it and that each adversity or difficult situation that we go through is a new opportunity to trust God more.
Let us remember that faith is illogical and always involves an element of risk but from it we always obtain the richest blessings and this is what the psalmist describes in this psalm full of trust and faith.
Saying this psalm and pronouncing it is very easy, but the problem is not in saying it but in believing in practicing it and making it a lifestyle.
This refreshing and motivating psalm describes and reflects the absolute trust in God even in the worst scenarios who truly has the conviction that Jehovah is his shepherd and he will really lack nothing because he has understood that in addition to believing in God he believes in him as a father and your confidence is rooted fully in your word
