You should be certain not only that everything happens by God’s providence but also that the providence of God reaches down to even you, to ensure your protection.
Once this foundation has been laid, that is, when you by faith take hold of Christ this guarantee, who died for you, rose again, rules all things at the right hand of God, and in whom all promises are Yes and Amen (2 Corinthians 1:20), we can look together at some more promises of God.
Psalm 91:1 puts it so beautifully:
He who dwells in the shelter of the Most High
Will abide in the shadow of the Almighty.
2 I will say to the Lord, “My refuge and my fortress,
My God, in whom I trust!”
3 For it is He who delivers you from the snare of the trapper
And from the deadly pestilence.
4 He will cover you with His pinions,
And under His wings you may seek refuge;
His faithfulness is a shield and bulwark.
5 You will not be afraid of the terror by night,
Or of the arrow that flies by day;
6 Of the pestilence that stalks in darkness,
Or of the destruction that lays waste at noon.
7 A thousand may fall at your side
And ten thousand at your right hand,
But it shall not approach you.
8 You will only look on with your eyes
And see the recompense of the wicked.
9 For you have made the Lord, my refuge,
Even the Most High, your dwelling place.
10 No evil will befall you,
Nor will any plague come near your tent. (read the entire Psalm)
Likewise Isaiah 49:14-16:
But Zion said, “The Lord has forsaken me,
And the Lord has forgotten me.”
15 “Can a woman forget her nursing child
And have no compassion on the son of her womb?
Even these may forget, but I will not forget you.
16 “Behold, I have inscribed you on the palms of My hands;
Your walls are continually before Me.
Think of this! God constantly has His attention on you, His adopted child. “Behold, I have inscribed you on the palms of My Hands.” You are a very important person in His eyes.
Note also Psalm 55:22 “Cast your burden on the Lord, and He shall sustain you; He shall never leave the righteous in trouble”; 1 Peter 5:7 “Cast all your cares upon the Lord, for He cares for you”; Romans 8:28 “We know that all things work together for good to those who love God.”
As Dr. Caspar Olevianus put it nearly 500 years ago:
Finally, have your heart take hold of the final farewell and departure of your Savior and Head, Jesus Christ, and remember that it is still in effect today and all the days of your life — in the labors and trials of your vocation, in things pleasant and unpleasant: “Lo, I am with you every day, even to the end of the world,” says Christ the Lord (Matthew 28:20).
