Christians exercise through resisting temptation, enduring trials, serving others, and telling others about our faith. We need to be pushed to stay strong. This means exercise. Temptation and problems test our character; serving others stretches our faith; telling people about Christ strenghtens our devotion.
Christians rest through worship. Our world has a tendency to tighten us, like a rubber band being pulled to the limit. Unless we take time weekly (and daily!) to recognize and worship God, he won't have the opportunity to minister to our needs.
We need sleep, rest, and times of vacation to get our physical batteries recharged. In the same way, we need worship to keep us spiritually renewed.
Spiritual growth takes time-a lifetime! This means growing in relationship, not just changing our behavior. Growing a strong Christian life means learning how to love the person of Jesus Christ more each day, staying close to him and getting to know him better.
Ephesians 5:11 Take no part in the worthless deeds of evil and darkness; instead, rebuke and expose them.
5:15 So be careful how you live, not as fools but as those who are wise. 16 Make the most of every opportunity for doing good in these evil days. 17 Don't ask thoughtlessly, but try to understand what the Lord wants you to do. 18 Don't be drunk with wine, because that will ruin your life. Instead, let the Holy Spirit fill and control you.
