Armenians,
We most certainly can be sure that we are the elect and have eternal life!
"*Knowing*, brethren beloved, your election of God." (1 Thess. 1:4)
"These things have I written unto you that believe on the name of the Son of God; that ye may *know* that ye have eternal life, and that ye may believe on the name of the Son of God." (1 John 5:13)
Yes, Paul compared the Christian life to a race (Heb. 12:1), but in order to enter the race of faith one must be saved by the grace of God. Christians run the race of faith in order to obtain rewards, not eternal life.
"Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible." (1 Cor. 9:24-25)
v.25 is clear that Christians are running to obtain crowns and rewards, NOT eternal life. (cf. 1 Cor. 3:14-15)
If one is trusting in his or her own works to get them into heaven, they, my friend, are on the wrong way!
"But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away." (Is. 64:6)
One's works get them no where with God. The only way to the Father is through the His Son!
"Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me." (John 14:6)
If a man tries to get to the Father any other way except through His Son, the Bible that man is a thief and a robber!
To God be the Glory, Christopher
