"Therefore, brethren, be ye steadfast, unmoveable. Firm as a rock, devoted to Christian life, for their faith is not vain." - 1 Corinthians 15:58
Too many Christians become unsettled, weary, and unhappy with were they are in life. These people give up, change churches, blame others (spouses, family, pastors, other Christians), or even blame and turn their back on God. The problem is not all of these external things listed above, it is internal. The real issue is that they do not have patience and do not use their faith -- rather than press on towards their divine destiny, which was right in front of them; they retreat and push their destiny further from them. There is a quote by Gordon Lindsay that fits perfectly with this, he said "Don't dig up in unbelief what you planted in faith."
