It is important to Preach Jesus Christ , who He is and what He accomplished. Any other Focus is "another Gospel " which Paul warned about, even Cursing those who preached it. Any preaching that does not Magnify God ( point out His Love , His Grace , His Mercy , His Perfection ) is wrong.

Galatians 1:6-9
6 I marvel that ye are so soon removed from him that called You into the Grace of Christ unto another Gospel :
7 which is not another; but there be some that trouble You , and would pervert the Gospel of Christ .
8 But though we, or an Angel from Heaven , Preach any other Gospel unto You than that which we have preached unto You , let him be accursed.
9 As we said before, so Say I now again, If any man Preach any other Gospel unto You than that ye have Received , let him be accursed.

1 Corinthians 2:2
For I determined not to Know any thing among You , Save Jesus Christ , and him crucified.

Ephesians 2:8,9
8 For by Grace are ye Saved through Faith ; and that not of yourselves: it is the Gift of God :
9 not of works, lest any man should boast.

The Gospel of Jesus Christ is Found here:

John 3:16,17
16 For God so loved the world, that he gave his Only begotten Son , that whosoever believeth in him should not Perish , but have everlasting Life .
17 For God sent not his Son into the world to Condemn the world; but that the world through him Might be Saved .
