There are only two possible ways for a person to be alive spiritually. That's right, I said two ways.
The first way is for a person to live his entire life without sin, that is, for him to live 100% of his life according to the standards of God. It is possible! Jesus did it, and in so doing, proved to sinners that it could be done (2 Cor. 5:21; 1 Pet. 2:22; Heb. 4:15; 7:26; 1 Jn. 3:5; etc.). In addition to Jesus, there are the exceptions of human beings living within the wombs of their mothers, newborn babies, and those having a mental defect which prevents them from knowing right from wrong. However, if you are reading this, I doubt very seriously you have met any of these qualifications.
To those who would challenge me on the basis that the Scriptures say "all have sinned" (Eccl. 1:20; Rom. 3:23; 5:12; 11:32; Gal. 3:22; etc.), I would suggest that, with the exception of Jesus, none of those mentioned above are capable of sin. The two biblical definitions of sin are: 1) not doing what you know you should do (Jam. 4:17); and 2) doing something you know you should not do (1 Jn. 3:4). The key is in the "knowing."
The second way is for a person to be alive spiritually, is for him to be spiritually born again (Jn. 3:3-8). When the Holy Spirit moves upon a lost person, He reveals to him that he is a sinner, and that Jesus died for his sins (Jn. 16:9; 1 Cor. 15:3-4). Believing the Gospel, and trusting in Christ, he is made alive spiritually (Rom. 6:4; 1 Cor. 15:22; Eph. 2:1, 5; etc.). In other words, he must be convicted concerning his condition (Jn. 16:7-11), he must be convinced that the Gospel is true (1 Cor. 15:3-4), and if he is truly born again, he will be grateful enough to Jesus that he will allow Him to be the Lord of his life (Rom. 10:9-10).
Is Jesus the Lord of your life?
If not, why not?
