We are compelled to preach the Gospel in the GreatCommission Mar 16:15. You overcome by the WordOfYourTestimony and the blood of the lamb Rev 12:11.
Remember, it is ChristInYou that manifests the testimony of Jesus Christ by the power of the HolySpirit.
If you don`t exercise the WordOfYourTestimony you may, in fact, not have one.
Draw near to the Lord and He will draw near to you Jam 4:8. Love the Lord and He will love you more by manifesting Himself to you and through you Pro 8:17 Rev 3:20.
When you exercise your TestimonyOfJesusChrist there will be people who receive it and people who reject it.
Those who receive it will love you for sharing.
Those who reject it will hate you as they hate the Lord Jesus whom they reject. Such people will persecute you as a defensive mechanism to justify themselves in their rebellion.
Let your TestimonyOfJesusChrist flow out of the HolySpirit in you. In so doing, your testimony will be delivered in power and authority by Him.
