As Christians, we have been adopted into the family of God  (Ephesians 1:5).  The result of this is that we have access to God as our Father.

Romans 8:15 (ESV)
¹⁵For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!”

The fact that we are children of God, realizing that we are such by way of adoption, should remind us of how much God loves us.  God did not adopt us because He had to, but Paul said He did so “according to the purpose of His will.”  God wanted to adopt us, and He wanted to because He loves us.

1 John 3:1 (ESV)
¹See what kind of love the Father has given to us, that we should be called children of God…

Since God is our Father, we can be sure that we have the Father’s love, which means that He is going to take care of us because that is what fathers do.  We see this with all good fathers.   Why would we think that earthly fathers love and care for their children more than God does His?

Matthew 7:9–11 (ESV)
⁹Or which one of you, if his son asks him for bread, will give him a stone? ¹⁰Or if he asks for a fish, will give him a serpent? ¹¹If you then, who are evil, know how to give good gifts to your children, how much more will your Father who is in heaven give good things to those who ask him!

We can trust the providential care of God not only because He is our Father, but because He is a good Father.  Does He give us everything that we want?  No, good fathers do not do that.  Parents who spoil their children by giving them everything they ask for have not learn how to love with proper discernment.  This is a lesson even brethren have to learn in their dealings with each other.

Philippians 1:9 (ESV)
⁹And it is my prayer that your love may abound more and more, with knowledge and all discernment,

God has a discerning love.  He knows when to say no to us.  However, while God knows when to say no to our wants, He never withholds what we need.

Philippians 4:19 (ESV)
¹⁹And my God will supply every need of yours according to his riches in glory in Christ Jesus.

This is an example of the goodness of God.  Supplying our needs is not a matter of justice.  It is not a case of giving us what we deserve or a repayment of any debt.  It is God, out of the goodness and grace of His heart, and His steadfast love, taking care of us.  Because God is good, we never have to worry about our needs.  He, according to Paul, supplies every need we have.  What a load off our minds.  We do not have to worry about what we are going to eat or drink, or about what clothes we are going to wear, because God will provide all those things for us (Matthew 6:25).

There is one condition, however.  Before I give the passage that states it, let me ask you this.  If an earthly father told his son, I will give you a place to live, food to eat, and clothes to wear, as long as you abide by the house rules, would you think that was unlovely or the responsible thing to do?  I am sure that you would view that father as being responsible, teaching his son the importance of things like authority, respect, and accountability.  So, is it wrong for God to provide for us conditionally?  Of course not!  He will provide all of the necessities of life for us as long as we abide by the house rules.  What are those rules?  Jesus tells us.

Matthew 6:33 (ESV)
³³But seek first the kingdom of God and his righteousness, and all these things will be added to you.

This is the rule in the house of God.  We must seek God and His righteousness first.  If we do this, He will do the rest.  Why?  Because He is good.

As you wind down for the night, think about these things.
