Security: All things work together for good.

Romans 8:28 ESV
28 And we know that for those who love God all things work together for good, for those who are called according to his purpose.

This is one HUGE promise that can bring courage, faith, peace and joy in almost any situation. When a new believer begins to comprehend this verse, they have no option but to take it by faith. It is too big to reason out in our minds. After growing in our faith, and learning God's word, we gain more confidence in this promise. This confidence is not due to our being able to understand how it works. Rather, our confidence comes because His word has taught us who He is and what He is doing, and all this teaching only made possible by the Holy Spirit.

A short analysis of this verse:
We know - not wishful thinking, but knowing with no reason to doubt.
For those who love God - This is not just any person. They must be saved and have a living relationship with Jesus Christ. Romans 8:5 tells us that this 'love of God' is shed abroad in our hearts by the Holy Spirit. That is only for believers.
all things - Yes it means all things. Everything that comes into your life - blessings, opportunities, trials, sickness, poverty, friends, enemies, kind family, mean family, new life and death, little tiny disappointments, major life-crushing tragedies. Because of God and His love for His children, and the fact that He is Sovereign, we really can trust that He will use each of these things for our good. We will trust Him to define good because He knows us better than we know ourselves.

Another source makes this statement: God's providence rules in such a way as to ensure everything that happens to us is working for our ultimate good.

called for a purpose - God's children are called for a purpose - even more than one. We are called to love and worship God, to serve and obey Him, to glorify Him with our lives here on earth and to worship and glorify Him forever in heaven.

If you are a Christian - read this verse, meditate on it and think about it until you can rest in the security of such a promise. The things that God brings to your life are not just circumstance. These things are hand selected by God and allowed to reach you for a purpose. It is for your good. Rejoice!

God Bless You,
