Jesus said to His disciples: "Not everyone who says to me, 'Lord, Lord' will enter the Kingdom of Heaven, but only the one who does the will of my Father in heaven. Everyone who listens to these words of mine and acts on them will be like a wise man who built his house on rock. The rain fell, the floods came, and the winds blew and buffeted the house. But it did not collapse; it had been set solidly on rock. And everyone who listens to these words of mine and does not act on them will be like a fool who built his house on sand. The rain fell, the floods came, and the winds blew and buffeted the house. And it collapsed and was completely ruined."
Hmm. "Everyone who listens to these words of mine and ACTS on them..." Thinking on that a bit. He does not say, "Everyone who just believes in Me" will enter the Kingdom, but that 'belief' must mean, in effect, ACTING, DOING and 'working out' that belief, that 'salvation.' It's not just a 'mental ascent' and or a heart 'belief' alone, with no action. It is not "faith" alone as James also tells us, but it is grace that saves us, and then that grace of a transformed heart/soul is evident in the working out of that faith/belief, resulting in actions of love and goodwill. Love generates good works, but not all good works stem from love. Many 'good works' can stem from pride. So we're to believe, but it has to be more than 'belief' alone, for even devils 'believe.' They not only 'believe' but they can quote scripture inside out and backwards. Remaining IN Christ is essential. We are constantly warned to 'remain in Him' for apart from Him we can do nothing, and will 'collapse' in ruin. Isn't it then also wise to not only remain in Christ as a personal effort, but also as a 'Church' and remaining in HIS Church, also then essential for our safety and salvation? For He and His Church are One. Dis His Church and you risk dissing the Rock of Salvation and you risk collapsing in ruin. Just a thought.
