Matthew 5:30 "And if thy right hand offend thee, cut it off, and cast it from thee; for it is profitable for thee that one of thee members should perish, and that thy whole body should not be cast into hell."
Doing everything for Jesus is a radical concept because it's so unlike everything else in this world. When you are living every breath, and every second for Jesus Christ it's not sins like lying or murder that often trip up your walk with Christ. Instead, often it's good things, that become too very good things and distract from your walk with God. In Matthew 5:30 when Jesus talks about cutting off your hand, he is not saying that because your right hand is bad. In contrast, God created the right hand to do many things for the body, help balance, and make many swift movements. What God is teaching is that even good things can become idols, and if a good thing becomes an idol you may need to get rid of it completely. Idols can be so many things that often appear to benefit us so much: money, relationships, talents, college.. the list could go on and on. But anything that we love more than God is an idol. Anything we let distract us from our relationship or time with God is an idol.
As Oswold Chambers writes " Jesus did not say that everyone must cut off the right hand, but- if your right hand offends you in your walk with me- cut it off. There are many things perfectly legitimate, but if you are going to concentrate on God, you cannot do them."
"In the beginning Jesus Christ has to check you from doing a great many things that may be perfectly right for everybody else but not right for you."
Everything must be approached through the eyes of Christ or everything will become distractions and hindrances. For something to succeed, we definitely need God's wisdom, power, and grace.
