They go from strength to strength [increasing in victorious power]; each of them appears before God in Zion. - Ps. 84:7
Weakness is not a celebrated trait in God's kingdom. There is nothing to be proud about being weak and lukewarm. The reason being that the name of God is synonymous with power, might and majesty. So you can't afford to be weary and weak in your pursuit of the kingdom and of your goals.
Yesterday's strength may not keep you firm for the mounting challenges of today. So you need to put on strength. Shake off weariness and lukewarmness. Be on your guard. Be ready to seize new opportunities and confront new challenges. Get religion about what you do today.
Appearing before God every new day gives you the allowance to exchange your weakness for God's strength. So don't drag your feet and allow the devil to bungle your chances of winning through the day. May you experience the mighty power of God to do exploit as you go in Jesus name.
