There are many today who have a psuedo salvation, they think they are saved, but aren’t, and they will find out at the end of their life, but then it will be to late.
Matthew 7:22-23 Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness.’
The Apostle Paul says we ought to test ourselves to see if we are genuinely saved.
2 Corinthians 13:5 Test yourselves to see if you are in the faith; examine yourselves!
There are three tests that we can use to determine if we truly were born again in the past; one of the three is called “The Perseverance of the Saints.” This test basically says, “if you are genuinely born again and in God’s family you will run the race with endurance, you will finish well, you will not fall away.”
Colossians 1:23 if indeed you continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel that you have heard, which was proclaimed in all creation under heaven, and of which I, Paul, was made a minister.
Hebrews 2:1-3 For this reason we must pay much closer attention to what we have heard, so that we do not drift away from it. For if the word spoken through angels proved unalterable, and every transgression and disobedience received a just penalty, how will we escape if we neglect so great a salvation?
Hebrews 3:6 but Christ was faithful as a Son over His house—whose house we are, if we hold fast our confidence and the boast of our hope firm until the end.
Hebrews 3:12 &14 Take care, brethren, that there not be in any one of you an evil, unbelieving heart that falls away from the living God. . .For we have become partakers of Christ, if we hold fast the beginning of our assurance firm until the end,
Hebrews 6:4-6 For in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit, and have tasted the good word of God and the powers of the age to come, and then have fallen away, it is impossible to renew them again to repentance, since they again crucify to themselves the Son of God and put Him to open shame.
1 John 2:19 They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, so that it would be shown that they all are not of us.
It would be a good idea if you find yourself getting lukewarm, drifting away, or losing interest in spiritual disciplines to recommit to following Christ, don’t assume you are in God’s family when you may not be. The consequences of being naive in this area of our life are severe and eternal.
