On a side note, I personally think it is a wise thing to check our hearts. I know from experience, that if I ignore my inner thought life, my thinking can go askew. Unhealthy thinking can fester and before long our thought life can do downhill. If you are struggling, confide in someone that has a listening ear, and that can offer you sound counsel.
As water reflects the face, so one’s life reflects the heart.
Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day. For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen, since what is seen is temporary, but what is unseen is eternal.
2 Corinthians 16-18
He who oppresses the poor taunts their maker, but whoever is kind to the needy honors Him.. Proverbs 14:31
If we are rich and see others in need, yet close our hearts against them, how can we claim that we love God.. Romans 12:3
I urge you brothers and sisters, to watch out for those who cause divisions and put obstacles in your way that are contrary to the teaching you have learned. Keep away from them. For such people are not serving our Lord Jesus Christ, but their own appetite. By smooth talk and flattery they deceive the minds of naive people… Romans 16:17-18
