Matthew 15:8-9 (KJV)
8 This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me.
9 But in vain they do worship me, teaching for doctrines the commandments of men.
Let us be encouraged to examine ourself every day to ensure our heart is always right and near to GOD. When we do this and realise our heart has been wandering we can turn back to Jesus Christ and refocus our heart back to GOD.

When a heart wanders away one of the evidences will be that we start to teach our own doctrines and ways trying to excuse us or listen to others who teach doctrines of men. Another is when we are mindful of the things of men drowning our the things of GOD. “Matthew 16:23 (KJV) But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.”

One of the ways the LORD provided us a prompting so we do this, and this is the sharing and taking of communion as we can read in 1 Corinthians 11:23-34 (KJV)
“For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread: [24] And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. [25] After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. [26] For as often as ye eat this bread, and drink this cup, ye do shew the Lord’s death till he come. [27] Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. [28] But let a man examine himself, and so let him eat of that bread, and drink of that cup. [29] For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body. [30] For this cause many are weak and sickly among you, and many sleep. [31] For if we would judge ourselves, we should not be judged. [32] But when we are judged, we are chastened of the Lord, that we should not be condemned with the world. [33] Wherefore, my brethren, when ye come together to eat, tarry one for another. [34] And if any man hunger, let him eat at home; that ye come not together unto condemnation. And the rest will I set in order when I come.”
