Why do I care whether another sees my beliefs in my daily life?
In all things shewing thyself a pattern of good works: in doctrine shewing uncorruptness, gravity, sincerity, sound speech, that cannot be condemned; that he that is of the contrary part may be ashamed, having no evil thing to say of you. (Titus 2:7-8 KJV)
For none of us liveth to himself, and no man dieth to himself. For whether we live, we live unto the Lord; and whether we die, we die unto the Lord: whether we live therefore, or die, we are the Lord's. (Romans 14:7-8 KJV)
Whether I like it or not, because I am open about my religious beliefs, I am responsible for how I display them.
And, while I might be a 'fruit inspector': Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? ... Wherefore by their fruits ye shall know them. (Matthew 7:16, 20 KJV)
I am admonished not to be a judge:
So then every one of us shall give account of himself to God. Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way. (Romans 14:12-13 KJV)
Thus it is not just for myself, but for those who see my Lord through my life. For I have also been told:
Nevertheless, if thou warn the wicked of his way to turn from it; if he do not turn from his way, he shall die in his iniquity; but thou hast delivered thy soul. (Ezekiel 33:9 KJV)
I read of Christ's reaction for those who did not heed Him: O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not! (Matthew 23:37 KJV)
It's one of those that bore repeating: O Jerusalem, Jerusalem, which killest the prophets, and stonest them that are sent unto thee; how often would I have gathered thy children together, as a hen doth gather her brood under her wings, and ye would not! (Luke 13:34 KJV)
Some are warned, heed the call, but hold back from trusting God.
Then Simon himself believed also: and when he was baptized, he continued with Philip, and wondered, beholding the miracles and signs which were done. (Acts 8:13 KJV)
But it appears his belief was that Jesus was who He said He was, but Simon had not repented, was not forgiven:
Thou hast neither part nor lot in this matter: for thy heart is not right in the sight of God. Repent therefore of this thy wickedness, and pray God, if perhaps the thought of thine heart may be forgiven thee. (Acts 8:21-22 KJV)
How often do we look into the thoughts of our own heart and seek that forgiveness? Display it before other?
