We always start with the sure foundation which is Christ. Nothing can move this foundation. It is freely given by grace through faith. But we cannot spend the rest of our lives simply resting on that foundation. Don't worry. It will forever be there. But what we build on it is up to us.
Scripture teaches us that some will "suffer" loss when what we build is tried in the fire (1 Cor 3).
If what has been built survives, the builder will receive a reward. If it is burned up, the builder will suffer loss but yet will be saved—even though only as one escaping through the flames.
Scripture also teaches us that some Christians will be ashamed.
Be diligent to present yourself approved to God, a worker who does not need to be ashamed, rightly dividing the word of truth.
-2 Tim 2:15
And now, little children, abide in Him, that when He appears, we may have confidence and not be ashamed before Him at His coming.
-1 John 2:28
My brethren, count it all joy when you fall into various trials, knowing that the testing of your faith produces patience. But let patience have its perfect work, that you may be perfect [mature] and complete, lacking nothing.
In all these (and in many others) the way of wisdom was through testing, trial and suffering.
We look again at Hebrews 12 where we saw previously that we need to lay down the sin that so easily ensnares us and worldly desires that weigh us down; run the race and remember Christ suffered before us:
Therefore we also, since we are surrounded by so great a cloud of witnesses, let us lay aside every weight, and the sin which so easily ensnares us, and let us run with endurance the race that is set before us, looking unto Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.-Heb 12:1-2
The way to glory is the way of the cross.
[G]iving all diligence, add to your faith virtue, to virtue knowledge, to knowledge self-control, to self-control perseverance, to perseverance godliness, to godliness brotherly kindness, and to brotherly kindness love. For if these things are yours and abound, you will be neither barren nor unfruitful in the knowledge of our Lord Jesus Christ. For he who lacks these things is shortsighted, even to blindness, and has forgotten that he was cleansed from his old sins.
-2 Pet 1:5-9
You can have Your Best Life Now or Your Best Life Later.
We know Satan wants to devour us with religion and slavery to sin (these two feed each other). But we must also recognize the lure of the world and the weakness of our flesh.
- The lust, greed and covetousness of the flesh
- The lust, greed and covetousness of the eyes
- Our pride and selfishness
