Faith in Christ let us Come to God's Presence

Because of Christ and our faith in him, we can now come boldly and confidently into God¡¯s presence.
Ephesians 3:12 NLT
https://bible.com/bible/116/eph.3.12.NLT

Faith in Christ makes it so we can come boldly into God's presence.  We can come to God through Jesus.  We don't have to feel that we can't go into God's presence because we've done something wrong.  We can go into God's presence because of what Jesus did for us on the cross.

Jesus United Us with God Through His Blood

But now you have been united with Christ Jesus. Once you were far away from God, but now you have been brought near to him through the blood of Christ.
Ephesians 2:13 NLT
https://bible.com/bible/116/eph.2.13.NLT

God wanted us to be united with him after we sinned, so He sent Jesus to die for our sins and he paid the price with His blood so we could be united with God again.

God Has Shown us Grace and Kindness

So God can point to us in all future ages as examples of the incredible wealth of his grace and kindness toward us, as shown in all he has done for us who are united with Christ Jesus.
Ephesians 2:7 NLT
https://bible.com/bible/116/eph.2.7.NLT

God used Paul to show His grace and kindness and God points to both him and us as examples for future generations to see how God is so kind to us and gives us grace through Jesus Christ because He saved us by dying for our sins and rising from the dead.

People forget about God's grace and kindness because many of them have the image of God as being a mean, old man.  But God gives us both grace and kindness when we are united with Christ Jesus.
