It is important to always have the peace of the Lord in our hearts, because if we have the peace of the Lord in our lives, then wherever we go we will feel good and safe. God is with you. How to be in complete peace? The first thing is looking for Him every day, every moment, to be subject to His statutes, to obey Him and to make sacrifices in His name.
Only God is the one who can give us that peace that we need every day, that is why we must trust in walking under His divine will. The prophet Isaiah tells us about this:
Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.
The prophet Isaiah was referring to the fact that God was the one who was going to bring peace and care to all the people, to all those who believed and trusted in Him. “You will keep in complete peace”, that is, he was implying that only God is the one who can give that peace and love that every human being can have, that is why he refers to the people of Israel with these words, so that all continue to put all their trust in the Lord.
He told the people to persevere in their thoughts, that is, to only think about following the Lord, to guard against all kinds of bad thoughts, to do the divine will of the Lord.
So, brothers. Let us keep ourselves in the Lord, let us abide with good thoughts under the divine will of the Lord, and the peace of the Lord will always surround us.
