Some think religion and faith are just "a crutch for the weak-kneed". However, true religion and true faith are the solid ground beneath our feet. In an earthquake, or on thin ice, even the strongest fail to stand. Whether or not we walk on crutches, we all rely upon solid ground.
Eph 3:14-21
In Ephesians 3:14-21 we find that solid ground. This is a passage about full and abundant spiritual strength through faith in Jesus Christ. In this passage, there are what we might call three loves. These are our spiritual ground and source of strength.
1. The love of God —expressed in worship
Paul says (in verse 14),"I bow my knees". He is not a weak-kneed man, but a strong man on his knees. He glorifies the Father, Son, and Holy Spirit, in worship, as should the whole church family (verses 15 and 21). Jesus said, that to love the Lord your God with all your heart and soul is the greatest commandment (Mtt 22:37-38).
2. The love of one another —expressed in fellowship
Notice how Paul speaks of "the whole family"(verse 15) and "all the saints"(verse 18). Peter says simply, "Love the brotherhood"(1Pet 2:17). By sharing together in the knowledge and fullness of God we strengthen one another.
3. The love of the truth —expressed in doctrine
Doctrine means the teaching and learning of God’s truth. To comprehend (verse 18) and to know (verse 19) is to be strong. The expression "surpasses knowledge" means that the knowledge of God’s truth and love goes beyond the ordinary knowledge of man, and is revealed to us by God (1Cor 2:10,12). People who do not receive a love of the truth, who, in other words, refuse to love the truth, will be deceived by the antichrist (2Th 2:9-10).
Conclusion— By means of these three loves, God’s power works in us, so that we become grounded and strong, enjoying an exceeding abundance of blessing from the riches of God’s glory.
