"A merry heart maketh a cheerful countenance:..." Proverbs 15:13
For the righteous (saints/saved) we have the Holy Spirit within and SHOULD have joy within. So if we have joy, we should have a "merry heart".
Remember the children's song "If you're happy and you know it"? It says "if you're happy and you know it, then your face will surely show it...!" Does your face show how happy you are?? Take a look in the mirror...
Too often, those of us who are saved can't be distinguished from those who aren't because we don't show the joy within. Why don't we have that joy??
1. Are you walking with the LORD daily (reading your Bible)? "Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth." 2 Timothy 2:15
2. Are you praying? "Pray without ceasing." 1 Thessalonians 5:17
3. Are you in church? "Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching." Hebrews 10:25
Not doing these things will really take it's toll on the Christian's life. You won't be able to live a victorious Christian life if you aren't getting victory over the flesh and doing the things the Lord has instructed us to do.
"A merry heart doeth good like a medicine:..." Proverbs 17:22
