Ephesians 3:12 (AMP)
In Whom, because of our faith in Him, we dare to have the boldness (courage and confidence) of free access (an unreserved approach to God with freedom and without fear).

Access is the means, place, or way by which a thing may be approached, a doorway, or a passageway. Jesus said in John 14:6 that He is the way, which is the ultimate access in life.
Access to anything is a priority in life, we should be able to access services and facilities needed for quality of life. That is what life in Christ gives us, access to both an abundant life on earth and eternal life. We all need access in every area of life, and someone is always needed to open that door to admit us and grant us access to where we need to get to.
When a man gives us admission into a place we otherwise would not get into on our own, there is an expectation of repayment that may well be beyond our affordability.
It is only in Christ’s name we can come to God and no other can give us admission into places and things without expectations, but Christ Jesus and He has thrown open the doors of the temple or life according to Psalm 118:19, that we may enter and perform our vows unto the Lord.
Proverbs 18:16 says a man’s gift will make room for him, meaning that in certain quarters, the quality of material, physical or financial gift you have to offer, will determine which doors of society you can access and if you’ll be admitted into some places.
Esther had none of these but the God of Israel, who by divine mercy and grace granted her access into the palace as queen according to the book of Esther.
On other occasions, we may need to cry for access and ask the Lord to grace us access to the places He’s already prepared for us, like Joseph in Genesis, who needed to be in the palace but until the grace for access was released, for his gift to make room for him, he went through the period of crying- from Potiphar’s to prison until the door of admission into Pharoah’s presence was opened. Pharoah’s butler gave him access, but it was joseph’s gift that admitted him into the palace.
The Lord grace Moses divine access into the palace a helpless baby that when the time came, he would be admitted into pharaoh’s presence to perform his Godly duties.
There is nothing stopping anyone from coming to salvation, the sacrificial death of Christ has given everyone access to salvation, to the Lord and heaven according to Acts 14:12. Christ became the doorway to eternity when the curtain to the temple, by implication, the throne of God was torn from top to bottom, granting us open and free admission.
Romans 5:2 says Christ not only grants us access to the Father but introduction and admission to grace and favour and it is only through him that the privilege is continued. This access to God is an unconditional and lasting privilege, unlike the conditional and temporal access granted by humans.
Don’t allow fear, lack of confidence and ignorance to keep you from using the liberty of prayer and supplication, by faith in Christ to access what grace purchased and paid for on the cross, because Christ is our boldness and courage. You are graced for access.
Shalom
