In the beginning God created man in His image and likeness to live and fellowship with Him forever. This life, on this earth was not the primary goal of God, it is a tool and method of finding out who was worthy to live with Him, and to make them more worthy by means of trials and challenges.

2 Thessalonians 1:5This is a plain indication of God’s righteous judgment so that you will be considered worthy of the kingdom of God, for which indeed you are suffering.

2 Thessalonians 1:11 To this end also we pray for you always, that our God will count you worthy of your calling, and fulfill every desire for goodness and the work of faith with power,

Ephesians 4:1 Therefore I, the prisoner of the Lord, implore you to walk in a manner worthy of the calling with which you have been called,

It is an interesting concept in that we are counted as worthy by God because we counted ourselves as unworthy.

2 Corinthians 3:5-6 Not that we are adequate in ourselves to consider anything as coming from ourselves, but our adequacy is from God, who also made us adequate as servants of a new covenant,

Our worthiness grows as we serve God, doing his work, blessing people, teaching, praying, and giving.
