Our leaf will not wither. We will maintain our Christian walk with the same enthusiasm with which we began. Whatever we do will prosper or be successful - not the way the world judges success, but the way God judges it. One of the reasons for this, I believe, is that as we obey God s word and discipline ourselves to do his will, we feel good about ourselves - after all, this is what God created us to be. This translates into being confident in all our endeavors.
Confidence breeds success.
Also, we have a helper, the Holy Spirit, who, when we fail, will lead us back toward the road to victory. All these promises are made to the one who mediates on God and his word. Meditation is a result of discipline. We read the Bible, we pray, and we meditate. This means we must be willing to spend some quiet time alone with God.
