"But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil." -Hebrews 5:12-14
There comes a time in our Christian walk when we take responsibility for our faith. We begin to understand that our lives have meaning beyond what we can see right now. We realize it's not all about us, and we feel more confident in who God made us to be. We've grown up in the knowledge of God and of His character, and we have a better understanding of His will for the earth. We learn to fight for others who may not know God as well as we do.
Nehemiah was someone in the Bible who took responsibility for his faith. Check out his prayer to God on behalf of the nation of Israel:
"LORD, the God of heaven, the great and awesome God, who keeps his covenant of love with those who love him and keep his commandments, let your ear be attentive and your eyes open to hear the prayer your servant is praying before you day and night for your servants, the people of Israel. I confess the sins we Israelites, including myself and my father's family, have committed against you. ... Lord, let your ear be attentive to the prayer of this your servant and to the prayer of your servants who delight in revering your name. Give your servant success today by granting him favor in the presence of this man." Nehemiah 1:5-10
He went on to be the catalyst to begin rebuilding the wall of Jerusalem.
We begin to take responsibility when we see a problem, and we realize what it is God has placed in our hands. We don't have to be a certain age or of a certain stature to do this. Whatever it is is a means to bless others. Nehemiah took responsibility by praying and repenting on behalf of the nation of Israel. Then, he backed up his words with action — he began to rebuild the walls.
Have you taken responsibility for your faith? Are there things that you can do to act as God's representative and help to redeem the earth? Pray that God will give you the strength to do whatever it is He's called you to do.
