Mat 24:13 But he that shall endure unto the end, the same shall be saved.
There is and will be much we will have to endure until the last day when Christ returns.
Mat 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
Mat 24:30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
Mat 24:31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
John 6:40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
Within our self, that is the flesh, we are weak and easy to want to give up, but through God who will give us strength to endure will see us through all trials and tribulations as our focus has to be on Christ as we continue in the good works He left for us to carry on.
My prayer for you and all of us is that we remain in the Lord and trust Him in all things as in the end we will have the victory over the evil forces of this world.
